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.

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:
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.

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.

Importance of Satellite Communication Technology
There are artificial man made satellites revolving around earth which help us to communicate. In fact they help us in many ways. The television that we watch and the internet that we browse all work through the satellite technology. The technology is in fact used at all those places where the use of cables and wires is practically impossible.
It first and most important application was in inter country long distance telephony. These satellite phones get connected directly through geostationary satellite and then the signals are transmitted to teleport which is connected to a satellite phone system. The technology is used in the regions or places where the submarine communication cables and fiber optic cables is not possible.
The technology is also applied for television and radio broadcasting. Today the dish TV used widely is an improved version of the satellite technology which was given for the first time by Arthur Clarke in 1957. Since then it has improved a lot with dozens of channels for entertainment. The technology has thus benefited the entertainment industry hugely which has also grown and evolved into its present version giving range of entertainment to its viewers.
Technology is used in the military for communication. UHF radio links, global command and control system are some form of application of satellite technology for military communication. Besides this the technology is widely used for global positioning. This is helpful for mapping of regions. A detailed map of a particular region can thus be framed and used for various purposes. Satellite imagery has also gained much importance and is giving many benefits to the researchers in geographical field.
The technology is beneficial for forecasting of weather. With the improvement in technology and new advances being made the weather can be predicted with greater accuracy. This has its own importance as different research expeditions and explorations of various regions are dependent upon weather forecast. The airlines and similar mode of transportations are also dependent on accurate weather predictions.
There are satellite internet services used widely by the business enterprises. The satellite internet provides the enterprises to use VOIP feature. This feature is very important for the companies with branches in remote locations where broadband connections are too costly or are not possible to use due to geographic conditions of the region. The satellite internet thus provides for easy connectivity and prevents the company from all those financial losses due to the use of broadband connections.
Thus the technology has its own importance and is used widely in different fields benefiting us in different ways.

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:
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.
All such measures can be broadly grouped into following types:
- Authentication
- Authorization
- Confidentiality
