The Y2k Bug
.... around because computers might fail to recognize that it is the year 2000 versus 1900. The problem is going to affect the whole world.
How does the Y2K bug affect the average person? It is possible that the electric companyies’ computers could crash, which could cause either blackouts or brownouts. It would mean no heat for your house and no way to store perishable items. It would mean that water companyies could not operate, so there would be no running water. It could mean that grocery stores would have to be closed because they could not do any financial transactions. It could mean that banks would be closed and pe .....

Speech Recognition Technology
.... Schwab & Co., American Express, United Airlines, NationsBank, United Parcel Service, British Airways, and Sears Roebuck and Co. These companies focus on the fastest growing parts of the speech market, where the caller's voice replaces punching in letters and numbers on the telephone keypad. The other applications of speech technology are for the use of consumers. The users' voice can give computer commands as well as dictate speech into text.
All operating systems used today are Graphic User Interfaces (GUI's), but "future computers will have Speech User Interfaces, or (SUI's)" (Iversen, 3).
The sudden surge in s .....

Internet Censorship
.... every user wants his homepage to deal with the spin rates of atoms or the airspeed of South African swallows. Some users wish to display "objectionable" material on their homepages.
This may have started out as a prank to some, but now net- porn is an offshoot industry on the information superhighway. Companies like Playboy and Hustler run their own servers that are permanent parts of the internet, and on their pages they charge user to view Playboy and Hustler type material. What makes matters worse is evolution of the internet newsgroup system. USENET in its infancy was ARPANET's news and message component. Today USENET .....

Hate Groups And The Internet
.... concern to those hoping to keep the Internet a safe place for people of all ages to surf without the negative influences of such sites. There is however another side to the groups on the net, groups that attempt to provide both education and a positive influence on the surfers, groups which go from anti-hate sites to Green Peace and the world wildlife fund. So as the Internet grows in popularity and size it will become increasingly difficult to keep the so called hate sites off, without infringing on the rights of others, but it is also clear that steps need to be taken to ensure the goals of these sites are not achieved.

The Next Revolution In Music Technology: Make Or Break?
.... files on a computer. The audio files are near CD-quality and take up very little space on a computer’s hard drive. Previously, high-quality audio files were saved on a computer in WAV format, which takes up much more hard drive space than MP3. For example, a three-minute WAV file would use about 30 megabytes of disk space. But in MP3 format, the same song would use only two megabytes, leaving much more hard drive space available on the computer (which benefits the computer user).
Because MP3 files are typically less than five megabytes in size, they can be transferred very quickly and easily to and from anyone’s computer .....

The History Of The Internet
.... DOD, DOD's contractors, and the universities found that it provided a very convenient way to communicate (Wendell). The ARPANET was a success from the very beginning. Although originally designed to allow scientists to share data and access remote computers, e-mail quickly becomes the most popular application. The ARPANET became a high-speed digital post-office as people used it to collaborate on research projects and discuss topics of various interests. By 1971 the ARPANET grew to 23 hosts connecting universities and government research centers around the country ("Net Timeline.").
In 1973 the first international connectio .....

Technology And Progress
.... or stealing his food and running with it, but one time I took my games too far. For some reason I came in contact with the idea that pain was humorous, maybe from TV, or schoolmates, or even my older siblings. Despite where the idea originated I still was taken with this new form of humor. My dog Barney unfortunately was the recipient of my childish antics. Barney put up with it for the most part but gradually became further and further annoyed as the cruelty became greater. Somehow I believed the greater the pain that my dog received the funnier it was. Finally I came upon the thing that seemed to bother him the most, which .....

The Electronic Computer
.... 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 processing expanded enormously in the 1960s and has continued to increase at a rapid path ever since.
The computers of the 1940s to 1960s were complex, expansive machines that were practical only for .....

Advancement Of The Computer
.... about them in newspapers and magazines calling them “electronic brains” That will change the world. In 1953 IBM realized that a market existed for business computers. They introduced a total of 19 of these computers for businesses. The computers were very large, expensive, and needed a large staff of professional people just to run them. Punch cards were used to give the first generation computer data and instructions.
The second generation of computers existed from 1959-1963. The second generation of computers did not run on vacuum tubes but instead they used transistors. Unlike vacuum tubes, transistors were small, requi .....

“How To Computerize Your Accounts”
.... accounting system to a computerized accounting system you also need to forecast the future demands of your company. After all to survive in the business world you must anticipate the future and not react to the past. How do you know when it is time to make the critical transition? “It is when management finds itself unable to keep track of its business. Which products are profitable? Which are not? Which customers pay on time ? Which are delinquent? Having easy access to this data is essential to running a healthy and competitive business”(Stevens 106). When your company has grown so large that management no longer has access .....

Object Oriented Analysis
.... like any large, complex engineering system, by first building working paper models of the system before committing the resources for implementation. This allowed the user to visualize the future system. Most modern approaches have integrated some form of Demarco’s philosophy. The variation in approaches is based on the kinds of models that should be built, how they should be built, and who should build them. A generic model-based software-engineering life cycle is demonstrated in Appendix 1-A.
A concept that is reflected in most model-based software-engineering models is the concept of a ‘Separation of Concerns’. This g .....
