Different Types of Computer Crimes

The computer crimes can broadly be grouped into three types. This includes the use of computer either as a subject, object or instrument to commit the crime. Use of computer viruses to commit crime comes under the category in which the computer forms the subject for the computer crime.

Most common way of committing the computer crime is using the computer as an instrument for crime. Crimes such as child pornography, online harassment and cyberstalking come under this category of computer crimes.

The different types of crimes under above mentioned categories are phishing, hacking, designing computer viruses, identity theft, cyber stalking and misusing the computer time. Let's discuss them one by one.

This is the type of computer crime in which the data related to the personal information is stolen. This is done by tempting the users to submit their personal data on the illegal sites designed for this purpose which appear similar to some popular sites. This is also committed through e-mails. The user is tempted to enter the personal information such as credit card number, password and bank account details.

Identity theft
It can be financial identity theft or identity cloning. This is the most serious crime where the financial information of the user is stolen and is used by the fraud to steal the money from the account of the user. In identity cloning the fraud steals the personal details of the user and uses the details as false user. In commercial identity theft, the thief uses the credit card information of the user to commit frauds and crimes.

These are the one which slow down the computer operations and processing. The computer viruses are the computer programs that are designed to harm the computer and destroy the information on the system. They spread through the network or different removable disks, drives and CDs.

In this a person gains an unauthorized access into another system by breaking the security barriers. The criminal finds out the information about the password and gain an access into the private information and communication of the user.

In this type of crime the criminal uses the internet and other computer based communication ways to threaten or post obscene mails or damage data of the user. Such crime is usually committed through discussion forums, chat rooms or similar places of common meeting on the internet.

Misusing the computer time is also a type of computer crime commonly committed everywhere in the organizations and offices. The employee on the company time and money commit this crime by checking personal mails, playing games without the authorization of the company officials.

What Is ISO OSI Model

OSI stands for Open System Interconnection. The OSI standards were laid down by the International Organization for Standardization in 1984. The OSI model gives seven different layers through which the data must travel when it is transferred from one computer to another in a network.

These seven layers can be distinguished into two groups:
  • Transport set and
  • Application set
Application layer
This layer provides network service to the end users by directly interacting with the operating system or the application software. This layer interacts when you perform any activity on the network like-mail, request websites and transfer files.

Presentation layer
The data from the application layer moves to the presentation layer so that it can be into the standard format in which it can be presented to other layers so that they understand it and process it further. This is the sixth layer. The encryption and decryption of data takes place in this layer.

Session layer
This is the fifth layer. This layer controls the link between the users. The layer establishes and ends the communication between receiving and sending devices in the network.

Transport layer
This is the fourth layer in the model. Transmission control protocol and user datagram protocol are there in this layer. Transmission control protocol establishes the link between two devices in the network.

This protocol also keeps a track of the packets that need to be resend and delivered. This layer checks the errors in transmission. It also integrates the data from different application. This layer thus ensures transparent transfer of data to the upper layers.

Network layer
This layer decides how the data will be sent to the other computer in the network. Routing of the data packets to particular IP address, take place in this layer. This is the third layer in the model. Internet protocol is a network layer

Data layer
This is the second layer. The packets are sequenced in this layer. The data is divided or broken down into small size of certain bytes. These small sized data are called as the packets. All the information that you exchange with your friends or the web pages that you request move in packets till they are delivered to the recipient. These packets have a head, payload and footer.

The header contains the information about the length, synchronization, number, recipient address and the origination address of the packet. The payload contains the main information that is to be delivered to the destination address. The footer contains the bits that check the errors in delivery.

Physical layer
This is the first layer in the OSI model. This layer defines the physical characteristics of the network defining the mechanical characteristics and voltage levels of the network.
Different protocol stacks are formed by combining the different OSI layers into one layer. This model is considered as the standard model for network communication.

The Drawbacks of Podcasting

Podcasting is the process by which you can share the multimedia files with your friends over the internet. These files can be viewed on the portable media devices or on the personal computers. Podcasting thus combines broadcasting and iPod. You can broadcast your audio and video formats on the internet. Your friends can download these files on their portable MP3 or iPod and view them.

You can auto syndicate the music videos or audios on the internet and these music videos and audios can be played on the iPod. For podcasting you don't need to have an iPod. You can choose your own content and create your own syndicated videos or audio programs.

For this you prepare your own audio files in MP3 or WMA format. You then publish them which can be received as the RSS format by the subscribers. These files can be downloaded by the iPod users, cell phone users. All that you need for podcasting is laptop; a microphone, headsets, portable recorder and software that facilitate podcasting.

It first came into existence in 2000. Since then it is getting popular day by day. Podcasting provide many advantages to the users. By way of podcasts the users can share their views and information with others. They can now use their faces and voice to convey and share all the information they want with others.

But every technology has a darker side. This is true for podcasting as well. The process seems simple and innovative way that supports creativity and sharing of ideas. But as you create your own files you ignore the size. Some podcast files can be very large with most of them exceeding 75MB size. Thus the main problem is the bandwidth. Each time you download the file, it uses the bandwidth.

Now the web host has certain limits for the bandwidth. You can use only a certain limit of the bandwidth. Once your website reaches the limit your site will be shut down for the definite term. Or, the other way round is that you pay for those GB that you use.

The only way out is, find out how serious you are with your podcast. If you are serious enough then reach out the podcasting service that you can afford. Find out the bandwidth you have for the month and the extra charges that the service provider will charge you once you cross the limits.

If you are really serious and want people to listen to your podcast then save some money so that you can pay for those extra gigabytes that you use in a month.

About The Phonograph

Phonograph was the first device that was used to play the recorded sound. The phonograph ruled the decades before the radio and motion picture came into existence.

Leon Scott de Martinville was the first to design the sound recording device. This was in 1855 when the first recording device came into existence. Scott got the device patented in 1857. The device was called as the phonautograph and was used as a laboratory instrument to analyze the sound. This instrument gave a foundation for the playback devices.

Edison came up with the concept of sound recording and reproduction in 1877. Another French scientist Charles Cros worked on the concept independently but was unable to come up with the working model of the machine. Thomas Edison demonstrated the model on November 29 1877 and patented the machine. It was the tinfoil phonograph.

The phonograph was an assembly of a large mouthpiece, a cylindrical drum, a diaphragm and a stylus. This tinfoil phonograph was made of a cylindrical drum which was wrapped in the tinfoil. This cylinder was then mounted on the threaded axle. The mouthpiece was attached to the diaphragm which was connected to the stylus.

As the stylus moved on the rotating foil, a vibration pattern was etched on the surface. To playback the recorded voice, the mouthpiece was replaced by the reproducer.

The era from late 1870s to early 1880s was full of discoveries in this field. In 1886 graphophone was patented by Charles Summer Tainter and Chichester Bell. This device was an improvement of the phonograph. It had the wax coated cylinder which gave clearer recording. It used floating stylus which gave clear sound conversion.

In 1887, an American scientist, Emile Berliner improved the existing species of the phonograph and came up with more improved version which he called as gramophone. He patented the device in 1887. This gramophone as we all know used the zinc disc on which the stylus moved laterally and spirally and reproduced the recorded sound.

With improved versions hitting the market the concept of phonograph parlors came into existence. First such parlor opened in San Francisco. Such parlors resembled the music parlors of today. The customers could list their choice of the music titles and enjoy their request which was played on the latest phonograph at that time.

Soon the kinetoscope came into existence in such parlors. These were coin operated. Such kinetoscope flipped the preloaded photograph in front of the customer.

Later a clockwork motor was developed and added to the Bell designed gramophones. This design was called Gramophone Grand and was the retail concept that was given by Thomas McDonald, the manager of gramophone industry.

How to Save Gas through Cylinder Deactivation

Cylinder deactivation puts off the unneeded cylinders while you drive the car and thus reduce the fuel consumed by the car. This technology is safely applied to the V6 and V8 engines so that the engines use half of the cylinders while you drive your car. With this technology the fuel efficiency of your car increases and your car give greater mileage for the same amount of the diesel.

This technology was first used by General Motors in 1980s. The attempt was unsuccessful as the computer technology was not that advanced at that time. Today, it is used widely in vehicles to improve the fuel efficiency. In most of the automobiles the sensors are used which convey the message to the engine to deactivate the unused cylinders.

The technology makes the vehicle to work on less number of cylinders under light conditions like the one while driving on the highway. The extra cylinders are shut down but they are readily available on demand. This is under the computer control in your car which ensures that the power is available when needed.

The cylinder deactivation thus provides with greater flexibility to the cars improving the fuel efficiency. It is the part of the tool kit which is widely used in the automobile industry. It includes hybrid engine, the start stop technology and variable valve timing. The start-stop technology turns off the engine when the vehicle stops.

The vehicles come with improved hydraulic valve lifters, hybrid engines and improved engine tuning enable the vehicle to smoothly transform from the position of cylinder deactivation to the position of using all cylinders when the power is needed most.

The system in Honda comes as Variable Cylinder Management (VCM).This is applied for the first time in Accord with V6 engine. The technology enables the driver to speed the car on three, four or six cylinders. The usage depends on the driving conditions.

The technology was first introduced by General motors in mid sized SUVs such as Chevrolet TrailBlazer in 2005 model. This cylinder deactivation technology will be available in sixteen vehicles in 2008. It was in use in sports vehicles, pickup trucks and minivans. But recently the technology is extended to the passenger vehicles.

The technology turns off the unused cylinders when the car is moving at a set constant speed on a nearly flat surface of the highway. The technology is a way by which the car can be made to run extra miles with the small amount of diesel in the fuel tank thus giving you the improved mileage.

The Benefits of Digital Television

Digital television includes high definition television. It uses digital signals to give you the movie on your screen. This is in contrast to the traditional televisions which use analog signals to form the picture on the screen that you watch.

What makes the picture quality better in the digital television?

It is the digital signals that the television uses to give the movie on the screen. The screen of these high definition televisions have more number of pixels than the traditional television working on the analog signals. Due to this the picture that is produced on the screen is more sharp and clear as compared to that formed in the screen of traditional televisions working on analog signals.


These televisions work on small bandwidth and give the advantage of multicasting and datacasting to the broadcaster. By multicasting the broadcaster is able to broadcast the programs to different viewers at the same time. It is like storing several files on one single DVD. The broadcaster similarly is able to broadcast several programs on one channel.

The broadcaster or the cable system operator can cast data on the channel along with the programs. Thus it gives the advantage to the cable operator to display different type of information which may be related to the price changes in the merchandise store or the list of the programs that are about to be shown.

You can use the scart lead to record the programs on the digital television. If you have some important appointment when your favorite program is aired or have to go shopping then all you have to do is get a digital video recorder that provide you with the facility to record the programs so that you can watch them later. But just check the capacity of the DVR to record the live TV. They come in different capacity and you can buy them on the basis of your choice and requirement.

You watch more number of channels than on your analog television. The picture is clearer, sharp with high resolution, the sound quality is more superior and picture and sound quality is little affected when there is a storm or the weather goes bad.

If you want to enjoy the experience of digital view on your analog television then you need a set top box or a converter which function by converting the digital signals to the analog so as to form a picture on your analog television. You attach the converter to your television and set the antenna so that you enjoy the show.

What is Digital TV?

The term digital television includes a host of terms associated with it - high definition television, datacasting and multicasting, interactivity and so on. The digital television offers many advantages over the analog televisions. Digital TV provides the broadcaster with the benefit of sending and receiving the videos and sound by data signals. This ensures better picture quality and sound quality.
The digital TV provides the broadcasters the facility of multicasting which gives the user multiple choices for programming. The pictures and videos are clearer and the quality of sound is greatly enhanced.

How the digital TV works?

The data for the channels is coded into digital signals. This is coded into binary codes of one and zero. These codes are compressed and transmitted through the transmitter. These signals are then taken up by the antenna and decoded by the decoder in your television to movie and sound.

This digital stream thus generated requires less space. Thus due to this reduced bandwidth that the digital streams require, other services can be used besides the television services. Such services falling in non television category include multicasting, interactivity and pay-multi media services. Thus the technology besides giving the clear quality movie and sound also helps the user to use different services.

In contrast to the digital signals the analog signals are send continuously even if there is no information that is to be sent. This is the benefit that digital television gives over the traditional analog televisions.

How to watch digital channels on your TV?

If you have your old television set then you need some hardware to enjoy the digital channels. For this you need a set top box and SCART lead. The boxes come in variety of costs depending on your need and craving for the digital channels. Such setups with analog televisions do provide you with the digital channels on your TV but the quality is not that refined as you get to see in the digital televisions available in the market today. The digital televisions today come in different forms:

  1. Enhanced digital television: gives you quality picture with Dolby digital surround sound.
  2. High definition televisions
  3. Standard definition televisions
If you are looking for a freeview then you just give a one time payment and enjoy around thirty channels for free besides few other features. But if you are considering taking the subscription service then you need to compare the costs of different service providers and your requirement before opting for any one among them.

Things to Know About Silver Nano Health Technology

Silver nano technology is based on the concept of destroying the bacteria by the use of ionized silver particles. The technology is used in range of electrical appliances like washing machines, refrigerators, vacuum cleaners and air conditioners.

Samsung launched its washing machine which claims of releasing several silver ions during the wash cycle that inhibit the bacterial cell growth and destroy the bacterial cells thus making the clothes germ free and bacteria free. The clothes also get coated with thin layer of the silver ions so that the clothes remain bacteria free for the next thirty days after the wash.

As the silver is effective in killing the bacteria hence it is effective in controlling the bad odors which is in turn caused by the bacterial action on food or other such organic matter. This property is thus used in coating the inner layers of the refrigerators. The Samsung has extended this technology application in their refrigerators by coating the inner walls of the refrigerators so as to keep the fridge free of odors, bacteria and fungus.

There are computer keyboards, mouse and laptops coated with such silver layer so as to make the computer germ and bacteria resistant. A South Korean company is using silver nano colloid technology in its appliances which release silver particles and purify the water that is germ free.

This water can be used for sterilizing different utensils and appliances used frequently in our homes and are considered to prevent us from different infectious diseases like infection of eye and illness. The water can also be used in the preparation of the cosmetics due to its germ free nature. In fact the sterilized water can be used any where for any purpose.

The company also has air purifier working on the same technology and releasing both positive and negative ions to purify the air around in our home. The silver nano perfume ejector can purify the air and make your room smelling clean free of bacteria. It also eliminates the bad odor in the room by using the water particles in the room air and releasing the silver ions that kills bacteria and sterilize the room air.

Although the technology has the benefits of sterilization but the wider application is questioned by the scientists and the researchers who are still not sure of its effect on human being. The environmentalists are also concerned with the use of technology as the released silver ions will effect the biological purification treatment of the sewage and waste water.

Network and Internet Security

Firewall, Digital Signatures, passwords, antivirus software and digital certificates are some of the network and internet security measures that we use to keep our network and computers safe from different types of viruses, Trojan horse, hackers, password thefts and similar type of security threats.

All such measures can be broadly grouped into following types:
  1. Authentication
  2. Authorization
  3. Confidentiality
Authentication is the method of confirming that the name and the password or the identity of the person trying to access the information is valid. By authorization the computer determines whether the person seeking information should be given privilege to access it. Digital signatures and biometric devices are the authentication forms used by the computer network.

Digital signatures are the signatures that ensure the identity of the sender and also that the original content of the data received is unchanged. These signatures cannot be copied by other person and ensures that the data sent is unaltered. Thus the signature besides being transportable is ensures the validity of the information and thus forms an authentication method. Digital certificates on the other hand are e-credit cards issued by the certification authority. These are used when performing the business transactions online. The digital certificate contains digital signature, name of the sender, a serial number assigned to the sender, the expiry date and the copy of the public key of the sender.

The digital signature and the certificate work on the concept of encryption and decryption and the use of public and private keys. In this the text is converted into the ciphertext, which can only be decoded by the use of the key. The public key is known to all the individuals while the private key is known to the sender of the message.

Other type of security measure most commonly used is firewall. A firewall acts like a wall and prevents the malicious information from entering the network. It is software or a hardware which thus acts as a filter preventing the network from virus threats. It works by either packet filtering or proxy service or by inspection. By proxy service the firewall first retrieves the information send by the system and then passes it to the network or internet. By inspection it identifies certain parts of the packet called as the key parts and compares these key parts with the authentic information or data. By packet filtering it examines each packet of information against set filters thus providing only authentic data to be exchanged between the system and the network.

Thus where firewall and password provide access control, the digital signatures provide for authentication and encryption for the confidentiality and make the network more secure to work on.

Benefits of DVD Technology

Moving from the VCR to the CD and then to DVD, the technology has improved many folds. Earlier it was VHS tapes that were there to store the movies and made to play. Then came the small compact discs, commonly called as CDs. These were small, handy and can store music, games, and movies. But the major drawback was that the storage capacity was less and it require around 2-3 CDs to store a movie or favorite music videos.

DVDs an acronym of Digital Versatile Disc or Digital Video Disc are an improvement over the compact disc. They have large storage space and a large amount of data can be stored in them as compared to the CDs. There are other advantages also, such as:
  1. The DVDs can be written on both the sides. A feature above CDs where the data can be written only on one side.
  2. The DVD reader can read a CD also in contrast to the CD reader that cannot read a DVD.
  3. The storage capacity of the DVDs can be up to 4.5 GB in contrast to the CDs with storage capacity of a maximum of 700 MB.
  4. The audio and visual qualities are better over the compact disc.
  5. Attaching DVDROM driver to the computer enables one to enjoy the movie on the computer screen.
  6. Four forms of DVDROM are available: - DVD R, DVD+RW, DVD RW and DVD RAM. The last three type DVDs can be written many times as per your preference, while the DVD R can be written only once.
This technology gained importance in 1990s and since then it is revolutionizing the entertainment industry. Its first application was in the entertainment industry in the recording of the video and music songs. Later its use spread to the other application of storage as well.

An improvement in the DVD technology is the blue ray disc. Where the DVD disc is read with the red laser, the blue ray disc as the name suggests is read using blue laser. Thus a large amount of data can be stored in the blue ray disc as compared to the DVD discs. Moreover the data stored is of high quality as compared to that on the DVD disc in terms of picture clarity and music quality. Where the storage space of digital versatile l disc is 4.7GB, you can store about 25MB of data on single layered blue ray disc.

The DVD technology hence has improved over the years and who knows what the technology will be in days to come. Any ways, enjoy your favorite album on the small circular plastic disc.

Benefits of Water for Gas Technology

We all use water as a coolant in our cars. But what about using it as a fuel? Yes! That is possible with the hydrogen fuel cell technology. The technology is an innovative step to make our environment cleaner and our cars more ecofriendly.

The technology improves the fuel efficiency of your car by about 80%. All you need is a small kit which you have to attach to your car engine. The kit consists of the two electrodes. One electrode acts as anode and the other as cathode. The electrolyte is water. When a certain level of voltage is passed then the water splits into its components hydrogen and oxygen. Hydrogen gas is made to pass into the fuel tank where it is absorbed and the fuel combustion is enhanced. This improvement in the combustion of the fuel results in less pollutant emission in the atmosphere as you drive your car. Your car thus becomes environment friendly.

So, what make this technology advantageous over other alternative fuel technologies and the diesel? Well the benefits are many. Some of them are:
  1. The technology is environment friendly
  2. If you use it in your car then the fuel efficiency improves and you save your expenses on petrol or diesel
  3. The engine efficiency increases and thus the life of your car engine too
  4. The kits available can be adjusted with any type of the engine and can be removed when you wish to change your car.
  5. The parts of the kits are easily replaceable and available in the market. In case you have to change any part of your kit then you simply have to move to the market go to the shop selling the accessories and purchase the part that you want to.
  6. The maintenance cost is very low
  7. The mileage of your car improves and you run your car more distance, with the same quantity of petrol than you would without the fuel kit.
  8. There are other alternatives to petrol and diesel in the form of biofuels. But they have their own limitation. Like the fuel prepared from sugarcane, the sugarcane can be grown in certain climates. Besides the processing of the basic ingredient is required to get the end product-the fuel for our cars. All this is ruled out in the hydrogen gas or water gas technology as water is omnipresent and what is all required is to get it from the source nearby and fill the kit.
With all these benefits don't you think its time to renovate your car with this wonder kit and play a small role in keeping your environment clean and pollution free?

The Advantages Of The Bluetooth Wireless USB Adapter

Bluetooth is a wireless technology, using a small microchip, a portable device and a mobile. Your mobile and the device get interconnected by Bluetooth as soon as they come within the specific range.

The technology thus gives you short range connectivity using 2.4 GHZ radio waves, without the use of wires and different size of cables. But what you need is the Bluetooth USB adapter and the chip. This chip function just likes the cable wires but they use radio waves to connect and transmit the information.

Bluetooth USB is a small hardware device. Bluetooth adapters and the dongles are the small devices almost the size of your small fingure and they can be attached to the USB port in your personal computers. As you attach the dongle the computer automatically gets connected to the nearby mobile by Bluetooth. You can then use these settings to download the ring tones or wallpapers to your mobile.

How is it advantageous?
The first benefit is that you don't have to tangle yourself in those noodle strip wires and cables. You just insert the US dongle in the USB port and download the wallpapers or ring tones or the games to your mobile.

It is simple to use. You just need to be in the range of 10-15 meter distance, so that your devices get connected by Bluetooth.

It is safe to use. The devices with Bluetooth exchange the authentication details and get connected automatically.

The technology also supports the VOIP technology hence you can talk to your friends also.
When you are using the USB adapter on your personal computer, then you are in a way using the computer and the mobile technologies together.

Around 8 devices can connect within the piconet or Personal Area Network formed by the Bluetooth.

You can transfer the games, ring tones, songs, text messages, and files among the connected devices in the piconet at the speed of 1-2Mbps.

When you connect the Bluetooth USB adapter to your computer you make your computer Bluetooth enable. That means your computer can now exchange the authentication code with other Bluetooth enabled devices in the short range of the piconet and get connected wirelessly. Now you can coordinate the contacts on your desktop or print the sheets or transfer files.

Although the connectivity is affected if there are more devices within the piconet or there are any changes in the environment, but the advantages out power the demerits.

Microsoft Java Virtual Machine

What is java virtual machine?
It is in fact software that is platform independent. It means that it can be run on any type of operating system may it be windows or Linux.

How it works?
Java is an object oriented, platform independent, multi threaded, dynamic, portable, high performance programming language. In simpler words it is high level language with all the above listed characteristics. In java programming the codes that we write are the language codes that we understand. These end with .java extension. These are converted into the machine language by the compiler. The compiler generates the byte codes with the extension .class that can be interpreted by the java virtual machine. The java virtual machine then interprets these codes and performs the functions. The byte codes generated remain same irrespective of the operating system. This very nature of java makes it platform independent which makes it independent of the operating system on which it runs.

Although it was originally designed to run the java programs but at present several other languages can be made to run on it.

Java Virtual Machine is the part of the java platform which helps to run the programs that are written in java language.

What is Microsoft java virtual machine?
A technology that makes to run certain java based applets on the windows like Windows 95, 98, 2000, NT, XP, CE and all their versions. But it is absent in XP SP1a, SP2. This technology is included in some form of Microsoft internet explorer.

This software was developed by Microsoft for the third version of the internet explorer. Microsoft came with this concept to gain a competitive advantage in the growing technology. But later a suit was filed by Sun Microsystems claiming that the Microsoft was using their technology.

Soon there was an agreement between the two in 2001and the Microsoft after paying Sun Microsystems $20 million agreed to discontinue the MSJVM. As it was not possible for some organizations to discontinue the use of MSJVM within the time duration hence both the groups decided to extend the duration to 31 December 2007. The Microsoft was thus given the license to support the Suns java code source.

Since then Microsoft has taken measures to end the MSJVM in its various products and decided to discontinue its use in its new products. Microsoft will only fix the security related problems of its customers in future.

JSP Technology

JSP an acronym of Java Server Pages is the member of the java family. It is the technology that is used to design and maintain the web pages. As the java is platform independent language hence the pages that are designed are platform independent and use java applet.By using JSP the web designers can now develop the dynamic websites.

It has some advantages over the HTML used commonly to design the web pages. The HTML gives a static presentation of the website. The data is written every time if it needs to be updated. For example a popular site of any online retail shop has all the details of the products available under different categories, their prices, and other relevant details regarding the mode of payment and the shipment details. If any category of the product is to be added now then using HTML language the web designer has to now write all the details again. But if the site is maintained using the JSP then only thing required is to make the changes in the maintained data record. After the changes are made and stored the site gets updated automatically.

A simple HTML page can be made dynamic by embedding the java codes. The technology is also used to develop new javabeans. The page developed is converted into the java servelet and then is executed on the server.

The JSP pages are saved as .jsp and the java compiler uses these extensions to generate the servelets which are further processed and finally interpreted and presented in the form of dynamic pages. Thus it is a server side scripting language.

There are other benefits also like the user does not have to be a master in the java language. But what is required is to have a basic understanding of java and the HTML. The web pages are platform independent and dynamic hence can be run on any platform. This means that the presentation is separated from the content thus enabling the different users to view the same site or content on different platforms.

Some terms associated with the technology:
JSP page: text based document. The text is in two forms- static and dynamic static data can be expressed in any language like HTML, XML; the dynamic text is of JSP.

Implicit objects: These are the objects on the site that are created and relate to the page, content, request, session etc.

Hydrogen Fuel Cell Technology

When you use water to run your car then in fact you are using the hydrogen fuel cell technology. This technology is latest in the news and it is an attempt by the scientists and engineers to make your vehicle less polluting.

Although eighty years old but the technology is taking waves as it makes the vehicle more environment friendly besides being an alternative to the petrol and diesel, the main fuel on which our car and bikes speed on roads.

The technology uses the fuel cell that has two electrodes and water. As the electricity passes the water molecule is broken down into hydrogen and oxygen. This chemical process is called as electrolysis. The hydrogen gas thus formed is passed to the fuel chamber where it is absorbed and promotes for the more efficient use of the fuel that we are using. Such assembly of electrodes is available in the market in the form of kits. You can fix these kits to your car.

Although biofuel, vegetable fuel are available as an alternative technologies for petrol and diesel but these have their own limitations. It gets costly to develop biodiesel from sugarcane. The source of the diesel is produced in certain climates thus this also act as the limitation. But such restriction is ruled out in the hydrogen fuel technology as the water is freely available and can be electrolyzed to make your car more efficient. The efficiency is increased by 70%-80%. Thus your car uses less of the petrol emits less pollutant and thus become more ecofriendly.

You can also prepare these hydrogen kits in your own garage. Remember your school days when you performed various science experiments in the lab. It's all that exciting and simple. All you have to do is go to the market and purchase all the essential things. Follow the instructions on the instruction manual. If you don't want to experiment then you can directly purchase the assembled kit available in the market.

You can search the internet and you will get all the options, the different designs and their prices. Browse through the catalogue and purchase the kit online sitting comfortably in your living room.
So contribute a little to conserve your planet by using this technology. You will not only make your environment less polluted but also save a lot of money by saving on the petrol.

Make your pocket grow bigger and your environment better to breathe in by using this environment friendly hydrogen fuel cell technology.

What is Technology

We use mobile to communicate, watch television news to find what is happening around us, open our computers and browse the net, drive cars and bikes, go to the physician who examines us through all the machines and the equipments to find out what is wrong inside our body and gives the prescription. All this is technology that we are using. Broadly technology means the application of the theory into practice or for the practical purposes. It helps us to perform the work more easily.

Technology includes all the machines and tools and the way how we use them. Today when we use technology we generally mean computers, mobiles, cars, satellites, space ships, and many such types.

Although it existed in the prehistoric ages when man evolved and used the weapons of different types, but at today it has moved to heights, thanks to the scientific methods that gained importance in the fifteenth century. The technology is still developing today and newer technologies are fast emerging. The advancements are getting more obvious in information, medical, nuclear, energy, and robotics and in fact all things that we use.

Technologies like the Bluetooth, Global Positioning System, nanotechnology, artificial intelligence, biofuels, wireless communication, VOIP technology; blue ray technology, plasma technology and many more are being used and talked among us.

It is all around us in every sphere of our life and making our life better by helping us to carry on our activities so easily.

Say for example the most used technology among us, the internet. It has changed the way we perform our jobs.
  • Now we shop and purchase our essentials on the net
  • transfer money and check our accounts by just visiting the bank site entering our name and password
  • Talk to our friends, send them messages, search the books and journals and many more such functions
For business too it has benefited a lot:
  • The companies can save cash by keeping all the records and connecting the departments through intranet and internet,
  • track and manage inventory
  • conduct video conferences
  • use software to compare previous records compare them make a trend analysis and take decisions
  • Collaborate with various associate to form a virtual enterprise
The advancement in nuclear technology and space technology is making us to discover the atmosphere and life in outer space. The mobile technology helps us stay connected.

All these just form the tip of the iceberg named technology. A lot more is there in store. Just look around and discover.

What is Communication

Take a case where you are talking to your friend on the basic landline phone. You are telling your friend to do some work. Then your friend is the person who receives the message, you are the one who give the message and the telephone is the medium buy which both of you are connecting to each other. This is communication. It is all about connecting with others and sharing our ideas.

It is the process to convey the information from the sender to the receiver. Thus the communication requires sender, receiver and the medium through which the message is been conducted to the receiver. For the communication to be effective there should be a feedback from the receiver. If your friend does not say hello when the line connects then you will wonder whether your friend is there on the other side or not. This is feedback.

Communication can be verbal or non verbal. In verbal communication there occurs the exchange of words by way of talking between the sender and the receiver. The nonverbal communication involves the communicating through signs and signals. The traffic signal is the nonverbal type of communication between the traffic controller on road and you.

The word today has assumed a far broader meaning when it is connected to the word technology. It encompasses all those things that make us to communicate with others. The cell phones and the wireless technology, internet, the list is growing day by day.

Through internet we can communicate with others by writing e-mails, or chatting through the messenger. Latest in this is the VOIP technology by which we can make long distance free phone calls to our friends. In business it is used to conduct web conferences or guide the employees who are there on the field stuck with some objections of the clients.

By writing mails we can deliver the message instantaneously. Through chatting and discussion forums we can share our views regarding any topic with those sitting in their homes on some part of the globe. Internet has made all this possible.

The mobiles and wireless technology is connecting us irrespective of the place where we are. So we can talk to our family while driving our car. The cell phones are also getting transformed with new features. The service providers coming up with new services so that the communication does not break down and we can communicate in much better way.

Radio Frequency Identification Technology

As the name suggests, the Radio Frequency Identification Technology (RFID) is the one that uses radio waves to identify the object in the store or the book in the library or an individual at any place.

How it works

The technology simply requires a microchip, an antenna and a reader. The serial number is given to the object or the individual that gives them the identity. This microchip is attached to the antenna and the two together are called as RFID tag. As the identification signal in the form of radio waves are given by the microchip, the antenna helps in the transmission of these signals. The signals are then picked up by the reader. This reader converts the signals in the digital waves and transmits it to your computer that finally interprets them as image.

It is a modification of the barcode technology which is based on the line of sight concept. Also if the bar code gets damaged due to any reason then it becomes hard to identify the object. Such shortcomings are absent in the Radio Frequency Identification Technology as the reader can read the RFID tag till the tag is within the range of the reader and much faster than in the bar code.

The technology works on three frequencies: low, medium and high. High frequency transfer more amounts of data and is for tracing objects like moving cars, and in spying objects in long range. But it is highly expensive, requiring high energy. The low frequency RFID tag is used for inventory management within short range.

Where is the technology used?

Almost everywhere. The technology is finding its application in the health industry, warehousing, libraries, military, spy departments and many more.

The technology is recently been applied by the Wal Mart to manage its supply chain. It is finding application in the retail stores, warehousing and supply chain management so as to locate where the product is exactly, how much is there in store and also track the product from the time it is in the storage till it is supplied to the consumer.

In the hospitals the technology is used to track the patients as well as the machines. The technology is useful to track the patients who have undergone critical treatment and are needed to be monitored after they move out of the hospital. The equipments in different section of the hospital can also be located. This is done by placing or embedding a small microchip that give them a particular serial number or identification number.

What Is Bluetooth Technology

Technological advancements in the wireless communication are fast catching up and Bluetooth technology is one of them. Named after the Danish king, Harlad Blatand, Bluetooth, is the technology that uses short range radio waves at 2.4 GHz bands to connect the digital appliances, laptops, headsets, mobile devices and other portable devices, so as to have a wireless communication within a small area called as Personal Area Network (PAN).

This technology came as an innovation from Erricson. And gradually became popular with the teaming up of the other IT companies and the mobile phones, so as to provide a facility to their customers for wireless communication within their work places or their home.

This technology enables the performance of the various tasks using the mobile phones, laptops, digital camera within an area of ten to fifteen meters, which can get interconnected with each other using the Bluetooth technology, till they are switched on. Once the devices with Bluetooth come within this area range they get interconnected. Thus a Bluetooth headset having RS transceiver, protocol, connects to a Bluetooth device which is at 7 meter distance. Thus the easy use of VOIP technology is also a feature and advantage of Bluetooth.

Once the devices are in the range they automatically exchange the address and other authentication details and get connected wirelessly.

For a Bluetooth all that is required is a small microchip, a mobile device or a digital camera or a laptop or portable device, radio waves, GSM or CDMA feature in your mobile. The main function is of the chip which like the cables transmits the information to the receiver chip at a particular radio frequency. As the devices with Bluetooth come in a specific range of 10-15 meters they get connected creating a network. The network thus formed is called as Personal Area Network (PAN) or piconet.

Upto eight devices can connect within this range and data can be transferred at the speed of 1-2Mbps. The authentication by the user is at 128 bit encryption. One device within a piconet can be a part of other piconet which is enabled by timesharing.

So you can synchronize the calendar and your contacts on your personal computer and palmtops, exchange and share data between devices like PDA and desktop without the use of USB portals.

Bluetooth technology, as it develops over time and year will enable for a convenient wireless communication and task performance under a much wider area.
