.... The key board has in side it a small microprocessor this will scan the keyboard once every millisecond to check for changes in the current when the key is pressed the processor finds that the current has increased and reacts accordingly and the same when the current is depressed and the current decreases. Over the years many new types of keyboard have been thought up these are mostly more ergonomically designed than there older counter parts this is done in order to reduce R.S.I a problem that effects a lot of typists One of the most interesting keyboard is a device called a data hand this will take a combination of hand movement and .....

.... plays a big part in job security. If a potential employee comes along demonstrating outstanding computer skills, he or she may take a job that formerly belonged to another employee if that employee doesn't even know how to check his e-mail. A good computer class would teach the basics of computers: typing a document in a word processor, running a specified program, and using a modem to check e-mail and access the Internet.

Not only can a computer do all the things that are unique to computers, it can be a television and a radio as well. Computers have also at .....

.... gets their floppy disk contaminated, and risks getting this virus on their computer, which may not have good virus protection. On IBM-Compatible PCs, viruses will only infect executable programs, such as the .EXE and .COM files. On a Macintosh, any file can be contaminated. A disk can also be infected even without any files on it. These viruses are called BOOT SECTOR viruses. These viruses reside on the part of the floppy disk, or hard disk that store the information so that these disks can be used, and is loaded into memory each time the computer is booted by one of these disks. DON'T DESPAIR! Despite all of what h .....

.... 1970, Ken Thompson and Dennis Ritchie began to develop their own single-user, multi-tasking small operating system and they chose the name UNIX. Their initial goal was simply to operate their DEC PDP machines more effectively. In 1971, UNIX became multi-user and multi-tasking, but it was still just being developed by a small group of programmers who were trying to take advantage of the machines they had at hand. (In other words, this operating system that they were developing did not run on any machine made by Bell!) In 1973, Dennis Ritchie rewrote the UNIX operating system in C (a language he had developed.) And in 1975, the portability of the C .....

.... will have numerous positive implications for the station's continuing role as entertainer and educator. Furthermore, high-definition television (HDTV) will significantly enhance the beauty and complexity of all PBS's programming.

.... and music videos. Something about the combination of sex and computers seems to make children and adults for that matter, a little crazy. In an 18 month study, the team surveyed 917,840 sexually explicit pictures on the internet where pornographic. Trading in explicit imagery is now "one of thelargest recreational applications of users of computer networks." The great majority (71%) of the sexual images on the newsgrouls originate from adult oriented bulletin-board systems (BBS). According to BBS, 98.9% of the consumers of online porn are men. The women hold a 1.1% in chat rooms and on Bulletin boards. Perhaps because hard-core sex pictures are .....

Time Magazine gave national attention to the issue of Cyberporn. The title "On a screen near you: Cyberporn" was on Times July 3rd cover issue. this in a sense sent Washington into an uproar.

.... are uncovering is credible. Computers may make activities like filing or organizing much simpler, yet people are not using their own minds to accomplish certain tasks. Our minds are not going to grow if we depend on a machine to think for us. Yes, there is a plethora of information available to us on the Internet, but is anyone applying it to everyday life? Maybe so, but there is nothing like researching your interests through your own motivation. It is not hard to go to the library and read through books to gather information. The many people who read for leisure probably cannot imagine reading their favorite novel on the computer. One of t .....

.... system that deploys quicker than the blink of an eye. Crash sensors, located on the front of the vehicle or in the passenger compartment, measure deceleration, the rate at which a vehicle slows down. When these sensors detect decelerations indicative of a crash severity that exposes the occupants to a high risk of injury, they send an electronic device that monitors the operational readiness of the air bag system whenever the vehicle ignition is turned on. These are designed to inflate in moderate-to-severe frontal and near-frontal crashes. They inflate when the crash froces are about equivalent to striking a brick wall head on at 10-15 m .....
