.... at a blindingly fast rate. The newest technology from five years ago is literally obsolete today. Electronics are also being used for new purposes continuously. The Internet, or World Wide Web, is a relatively new concept of being “on-line�. This new project has opened a limitless number of doors for our society. Now anyone can use the Internet to communicate with anybody else in the world a lot faster and cheaper. Cellular phones have also appeared recently in the electronic world. These devices allow a person to be reached from practically anywhere. With cellular phones a person can, from then on, be in communication with the .....

.... bottom part had five beads and each bead had a value of one (same goes for these as well). As the origin is not known as to whom may have made the invention and since may ancient empires used it, some of the first to use it were the Chinese and so the credit has been given to them. Another invention that comes from the abacus and was used in a similar fashion was the soraban. The soraban comes from the Japanese who perfected it to there use. The soraban is slightly different in the fact that it has one bead on the top part or each place value, and has only five beads in each place value on the bottom part. Even though we now have cal .....

.... will interpret this as January 1, 1900- not 2000" (de Jager 1). The '19' is "hard-coded" into computer hardware and software. Since there are only 2 physical spaces for the year in this date format, after '99', the only logical choice is to reset the number to '00'. The year 2000 problem is unlike any other problem in modern history for several reasons. William Adams points out some of the most important ones. "Time is running out- the Year 2000 is inevitable! The problem will occur simultaneously worldwide, time zones withstanding. It affects all languages and platforms, hardware & software. The demand for solutions will exceed the supply .....

.... of telecommunication. This for is called the Drum Telegraph. The drum telegraph was developed as a means of telecommunication. The natives of Africa introduced drum telegraphy. This roaring of drums is how messages were spread for far distances. In similar state, the old China used a sort of drum telegraph which was that of the "Tamtam". This was a big, free hanging, circular metal plate. The keystroking, as it is called, of this plate would create a far-reaching audible tone. This is the drum telegraph and the start of telecommunication. Fire Signaling Fire signaling is another part of the telecommunication family. Also, t .....

.... a network consisting of a central computer (the hub) surrounded by terminals. In a star network, messages pass directly from a node to the central computer, which handles any further routing (as to another node) that might be necessary. A star network is reliable in the sense that a node can fail without affecting any other node on the network. Its weakness, however, is that failure of the central computer results in a shutdown of the entire network. And because each node is individually wired to the hub, cabling costs can be high.Ring networkRing Network, in computer science, a local area network in which devices (nodes) are connec .....

.... stimulate their interest in the computing field. First and foremost is the fact that computer software is a very important educational tool. Students in high schools experience computers for the first time through games and other entertaining software. These help develop youth's mental pathway in the way of logic, reflexes and the ability to make quick and concrete decisions [Lipcomb, 66]. The next step requires them to think more seriously about the machines. Secondary students learn the first steps in computer programming by creating simple programs. Here, the assistance of useful software is necessary. The computer software .....

.... of modems for PC, internal and external modems. Evolution of Modems In the last 10 years, modem users have gone from data transfer rates of 300bps to 1,200 bps to 2,400 bps to 9,600 bps to 14.4Kbps to 28.8Kbps to, and to 33.6Kbps. Now new modem standards are emerging, reaching speeds of up to 56Kbps. Unlike the 33.6Kbps modems being sold today, 56Kbps is a significant improvement over 28.8Kbps modems. Viewing complex graphics or downloading sound files improves significantly with 56Kbps. The modem experts keep telling us that we are about maxed out. For instance when the 28.8 modems where first introduced they said that we've rea .....

.... What kind of schedule does the employee feel constitutes telecommuting? Generally speaking, telecommuting is defined as spending at least one day out of a five day work week working in the home. Is one day home enough for the employee? Or, too little? How does the employer decide how many days to allow? Does the employee's job lend itself well to telecommuting? Some jobs, obviously, can't be accomplished using a telecommuting format. Does the employee have a good track record for working unsupervised? This relates back to readiness levels. An employee who isn't performing at a high readiness level should not even be considered as a ca .....

.... person across the street or in Afghanistan, the transfer rate is virtually the same. Furthermore, data files and computer applications can be sent via e-mail. Unfortunately, physical packages such as gifts or magazines cannot be attached to e-mail. On the other hand, the postal service can send any kind of physical package, from a magazine to a pool table, for a price proportional to its size. In addition, the postal service can also transfer data if it is placed on a disk or a CD-ROM. However, speed is a problem, thus origin of the term snail-mail. For example, The smallest letter can take from two days to two weeks to deliver, depending .....
