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

Ш Unit 10. Personal Computers

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. Also disable call waiting, it could disrupt your modem connection 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.

1. The organization of a microcomputer system is the same as that of a larger computer system. The microprocessor unit (MPU), usually concentrated in a single chip, consists of the control unit and the arithmetic logical unit. Internal memory

^ Английский язык. Основы компьютерной грамотности 142

is made up of random access memory (RAM) and read-only memory (ROM). Because RAM is only temporary storage, all microcomputers require some instructions to get started after they are turned on, and these are contained in ROM. A micro­computer includes both an MPU and internal memory.

The portion of the system software that is in ROM brings into RAM the additional instructions required to operate the micro­computer. Typically these instructions are stored on a magnetic disk; hence, they are called a disk operating system, or DOS. This start-up process is called bootstrapping*. ROM also con­tains other programs that help to make personal computers easy to use, such as a programming language. Computer games are also stored in ROM cartridges.

In addition to the MPU, RAM, ROM, and associated con­trol circuits, other components, called peripheral devices, are needed to make a complete microcomputer system. The prin­cipal peripheral units are: input devices, output devices, mass storage units, and communication components. Like a DOS, the programs that control the flow of data between a microcom­puter and its peripheral devices are a part of systems software.

The most common input device used with personal comput­ers is the keyboard. Most personal computer keyboards have extra keys that perform special functions and that can be used to control the movement of a cursor on a screen. A leverlike** device, called a joystick, is also used as an input device, com­monly for playing video games.

2. The CRT (cathode-ray tube) screen used with personal computers is called a monitor. Keyboards and monitors may be part of a single unit that also contains the microcomputer and the disc drives, or they may be separate units. Besides the mon­itor, the most common input units are dot-matrix and letter-quality printers. Dot-matrix printers are suitable for most mi­crocomputer applications. Letter-quality printers are usually used for high-quality office correspondence. Both types of print­ers are considered to be low-speed character printers.

Mass storage units are available over a range of capacities and access times. Floppy disks, or diskettes, are the most common mass storage media. They store patterns of bits on magnetically coated, flexible plastic platters. A floppy disk platter is sealed permanently in a paper jacket with a small window for reading

143 Unit 19. Personal Computers

and writing. Hard disk storage systems are also available. They may be fixed or removable. Some mass storage units contain both floppy and hard disk devices.

Low-cost modulator-demodulator devices, called modems, that allow microcomputer systems to communicate over tele­phone lines have become increasingly popular. Modems permit networks of personal computer owners to exchange information or to access large data banks. These data banks may be dedi­cated to special applications, such as law or medicine, or they may provide a variety of consumer services.

The personal computer can serve as a work station for the individual today. Moreover, as it has become financially feasi­ble to provide a computer for the individual worker, so also tech­nical developments have made the interface between man and machine increasingly "friendly", so that a wide array of com­puter functions are now accessible to people with no technical background.

A personal computer is a small computer based on a micro­processor; it is a microcomputer. Not all computers, however, are personal computers. A microcomputer can be dedicated to a single task such as controlling a machine tool or metering the injection of fuel into an automobile engine; it can be a word processor, a video game or a "pocket computer" that is not quite a computer. A personal computer is something different: a stand­alone computer that puts a wide array of capabilities at the dis­posal of an individual.

The first generation of true personal computers, which came on the market between 1977 and 1981, had eight-bit micropro­cessors; later introduced systems had 16-bits ones. Now 32-bit microprocessor chips are available, and soon they will be includ­ed in complete computer systems.

2. Прочтите текст и объясните, как вы понимаете термин «компьютерное программирование».


Programming is the process of preparing a set of coded in­structions which enables the computer to solve specific prob­lems or to perform specific functions. Theiessence of computer programmingjis the encoding of the program for the computer by means of algorythms. The thing is that any problem is ex­pressed in mathematical terms, it contains formulae, equations and calculations^ But the computer cannot manipulate formu­lae, equations and calculations. Any problem must be specially processed for the computer to understand it, that is — coded or programmed.

The phase in which the system's computer programs are written is called the development phase. The programs are lists of instructions that will be followed by the control unit of the central processing unit (CPU). The instructions of the program must be complete and in the appropriate sequence, or else the wrong answers will result. To guard against these errors in logic and to document the program's logical approach, logic plans should be developed.

There are two common techniques for planning the logic of a program. The first technique is flowcharting. A flowchart is a plan in the form of a graphic or pictorial representation that uses predefined symbols to illustrate the program logic. It is, there­fore, a "picture" of the logical steps to be performed by the computer. Each of the predefined symbol shapes stands for a general operation. The symbol shape communicates the nature of the general operation, and the specifics are written within the symbol. A plastic or metal guide called a template is used to make drawing the symbols easier.

The second technique for planning program logic is called pseudocode. Pseudocode is an imitation of actual program in­structions. It allows a program-like structure without the bur­den of programming rules to follow. Pseudocode is less time-consuming for the professional programmer than is flowcharting. It also emphasizes a top-down approach to program structure.

Английский язык. Основы компьютерной грамотности 148

Pseudocode has three basic structures: sequence, decision, and looping logic. With these three structures, any required logic can be expressed.
