Text 2. Application of Personal Computers

 

Personal computers have a lot of applications, however, there are some major categories of applications: home and hobby, word processing, professional, educational, small business and engineering and scientific.

Home and hobby. Personal computers enjoy great popularity among experimenters and hobbyists. They are an exciting hob­by. All hobbyists need not be engineers or programmers. There are many games that use the full capabilities of a computer to provide many hours of exciting leisure-time adventure.

The list of other home and hobby applications of PCs is al­most endless, including: checking account management, bud­geting, personal finance, planning, investment analyses, tele­phone answering and dialing, home security, home environment and climate control, appliance control, calendar management, maintenance of address and mailing lists and what not.

Word processing. At home or at work, applications software, called a word processing program, enables you to correct or modify any document in any manner you wish before printing it. Using the CRT monitor as a display screen, you are able to view what you have typed to correct mistakes in spelling or grammar, add or delete sentences, move paragraphs around, and replace words. The letter or document can be stored on a dis­kette for future use.

Professional. The category of professional includes persons making extensive use of word processing, whose occupations are particularly suited to the desk-top use of PCs. Examples of other occupations are accountants, financial advisors, stock brokers, tax consultants, lawyers, architects, engineers, educators and all levels of managers. Applications programs that are popular with persons in these occupations include accounting, income tax preparation, statistical analysis, graphics, stock market forecast­ing and computer modeling. The electronic worksheet is, by far, the computer modeling program most widely used by profes­sionals. It can be used for scheduling, planning, and the exam­ination of "what if situations.

Educational. Personal computers are having and will contin­ue to have a profound influence upon the classroom, affecting both the learner and the teacher. Microcomputers are making their way into classrooms to an ever-increasing extent, giving impetus to the design of programmed learning materials that can meet the demands of student and teacher.

Two important types of uses for personal computers in edu­cation are computer-managed instruction (CMI), and comput­er-assisted instruction (CAI). CMI software is used to assist the instructor in the management of all classroom-related activities, such as record keeping, work assignments, testing, and grading. Applications of CAI include mathematics, reading, typing, com­puter literacy, programming languages, and simulations of real-world situations

Text 3. A Modem

The piece of equipment that allows a computer to commu­nicate with other computers over telephone lines is called a modem. The modem allows the individual to access informa­tion from all over the world and use that information in every­day life. Connecting with banks, Automatic Teller Machines, cash registers to read credit cards, access travel agents, buy prod­ucts, e-mail, access databases, and teleconferencing, the mo­dems provide easy access to many services. Files can be trans­ferred easily, by uploading to another machine, or downloading to your own machine within a matter of minutes. The comput­er modem can be used as a telephone answering system, and documents can be faxed from one computer to another assur­ing fast and easy access to important documents.

A modem takes computer information and changes it into a signal that can be sent over telephone lines. The modem is a bridge between digital and analog signals. The computer is of the digital type, and the telephone using analog technology. The modem converts the "0"s and "l"s of the computer (off-on switches) into an analog signals modulating the frequency of the electronic wave or signal. The modem does just the opposite and demodulate the signal back into digital code. The modem gets its name from MOdulate and the DEModulate.

Most people believe that you need a separate phone line for a modem, but that is not true. Your modem and telephone can share one line, the problem arises when someone else needs to use the tele­phone while the modem is in use.

There are three kinds of modems — internal, external, and fax. All modems do the same thing, they allow computers to communicate through telephone lines. This lets computers ex­change information everywhere. Internal Modem is a circuit board that plugs into one of the expansion slots of the comput­er. Internal modems usually are cheaper than external modems, but when problems occur, fixing and troubleshooting the mo­dem can sometimes prove to be quite difficult. External Modem attaches to the back of the computer by way of a cable that plugs into the modem port. It is usually less expensive and very por­table. It can be used with other computers very easily by unplug­ging it and plugging it into another computer. Fax Modem can be hooked up to your telephone and used to send information to your computer. Your computer can also send information to a fax machine. Most computer modems are modems with fax­ing capabilities.
