.... and retrieve information. It is that we are using every day. The idea of an automatic computing machine can be traced back to the mid-nineteenth century. But it was only in the 1904s, when electronics was applied to the task of automatic computing, that fast, reliable computers became possible. Early computers were used mainly for scientific and technical calculations. In the 1950s, businesses, universities and government began using computers to store and process such nonmathematical data as orders, invoices, and personnel records. The use of computers for business data p .....

.... killed." To understand how the Internet, on which so many base their hopes for education, profit and international competitiveness, came to this pass, it can be instructive to look at the security record of other parts of the international communications infrastructure. The first, biggest error that designers seem to repeat is adoption of the "security through obscurity" strategy. Time and again, attempts to keep a system safe by keeping its vulnerabilities secret have failed. Consider, for example, the running war between AT&T and the phone phreaks. When hostilities began i .....

.... 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 world no matter where they go. For the next generation, electronics will certainly offe .....

.... hard cover of the disk must NEVER be touched, the magnetic disk inside, must be protected by the metallic sliding shield, the disk must always be within the temperature of 50° to 140° Fahrenheit and the disk must never be bought near a magnet! (3M Diskettes) There are many such hazards to computer disks. Problems caused by magnets are very common. A floppy can be damaged unknowingly if it is kept near a magnet, that may be in the open or inside any device, such as a speaker phone in computer speakers or stereo or a telephone. And becuase of the common use of magnets in everyd .....

.... 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 Bullet .....

.... their needs, while at the same time making themselves familiar with the new enhancements that increase productivity. Finally, the company must allow time for installation and training. When looking at the need to change from a manual accounting system to a computerized accounting system you also need to look at the future demands of your company. How do you know when it is time to make the change? When your company has grown so large that it no longer has access to the data used to make decisions, then it is probably time to switch to a computerized data management sys .....

.... (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital calculating machine. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector (Soma, 32). In the early 1800, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built into his machine were operations that included everything a modern general-purpose computer would need. .....

.... computer. This, many believe, will be the world's biggest media group, letting consumers tune into anything, anywhere, anytime. The most extraordinary thing about the multimedia boom, is that so many moguls are spending such vast sums to develop digital technologies, for the delivering of programs and services which are still largely hypothetical. So what is behind such grand prophecies? Primarily, two technological advances known as digitization (including digital compression), and fibre optics. Both are indispensable to the high-speed networks that will deliver dynami .....
