What can computers do тест 7

What can computers do?

Computers and microchips have become part of our everyday lives: we visit shops and offices which have been designed with the help of computers, we read magazines which have been produced on computer, we pay bills prepared by computers. Just picking up a telephone and dialling a number involves the use of a sophisticated computer system, as does making a flight reservation or bank transaction.

We encounter daily many computers that spring to life the instant they’re switched on (e.g. calculators, the car’s electronic ignition, the timer in the microwave, or the programmer inside the TV set), all of which use chip technology.

What makes your computer such a miraculous device? Each time you turn it, on, it is a tabula rasa that, with appropriate hardware and software, is capable of doing anything you ask. It is a calculating machine that speeds up financial calculations. It is an electronic, filing cabinet which manages large collections of data such as customers’ lists, accounts, or inventories? It is a magical typewriter that allows you to type and print any kind of document — letters, memos or legal documents. It is a personal communicator that enables you to interact with other computers and with people around the world. If you like gadgets and electronic entertainment, you can even use your PC to relax with computer games.

Unit 2 computer essentials

Exercise 1.Look at the picture and label the elements of this computer system. Then read the text What is a computer? and check your answers.

What is a computer?

Computers are electronic machines which can accept data in a certain form, process the data and give the results of the processing in a specified

format as information.

Three basic steps are involved in the process. First, data is fed into the computer’s memory. Then, when the program is run, the computer performs a set of instructions and processes the data. Finally, we can see the results (the output) on the screen or in printed form (see the diagram below the text).

Information in the form of data and programs is known as software, and the electronic and mechanical parts that make up a computer system are called hardware. A standard computer system consists of three main sections: the central processing unit (CPU), the main memory and the peripherals.

Perhaps the most influential component is the central processing unit. Its function is to execute program instructions and coordinate the activities of all the other units. In a way, it is the ‘brain’ of the computer. The main memory holds the instructions and data which are currently being processed by the CPU. The peripherals are the physical units attached to the computer. They include storage devices and input/output devices.

(floppy, hard or optical disks) provide a permanent storage of both data and programs. Disk drives are used to handle one or more floppy disks. Input devices enable data to go into the computer’s memory. The most common input devices are the mouse and the keyboard. Output devices enable us to extract the finished product from the system. For example, the computer shows the output on the monitor or prints the results onto paper by means of a printer.

On the rear panel of the computer there are several ports into which we can plug a wide range of peripherals – modems, fax machines, optical drives and scanners.

These are the main physical units of a computer system, generally known as the configuration.

Exercise 2. Use the information in the text and the diagram to help you match the terms in the box with the appropriate explanation or definition below.

From the first electronic digital computers of the forties to to-day’s versatile computers and most up-to-date microcomputers, very little has changed as far as basic computer operation is concerned. In the last thirty years, vast improvements in the size, speed and capabilities of computers have taken place. But to-day digital computers still use the same logical operations as their predecessors. There are many basic concepts that can be applied to all types of computers, including microcomputers.

For the most part, human beings can do whatever computers can do, but computers can do it with much greater speed and accuracy, though computers perform all the calculations and operations one step at a time. A computer is faster and more accurate than people, but unlike most people it must be given a complete set of instructions that tell it exactly what to do at each step of its operation. This set of instructions, called a programme is prepared by one or more persons for each job a computer is to do. These programmes are placed in the computer’s memory unit in binary-coded form, with each instruction having unique code.

Computers are often used in applications where the results of their calculations are required immediately to be used in controlling a process. These are called real-time applications; they are often found in industrial process control in industries such as paper mills, oil refineries, chemical plants, and many others. The measuring systems send their signals to the computer which processes them and responds with appropriate control signals to be sent back to the process.

Computers in present use range considerably: from tiny things to big fellows. The microcomputer, for one, is the smallest and the newest member of the computer family. It usually consists of several integrated circuit chips, including a microprocessor chip, memory chips, and input/output interface chips which are a result of tremendous advances in large-scale integration.

Minicomputers are larger than microcomputers, they are widely used in industrial control systems, scientific institutions, and research laboratories. Although more expensive than microcomputers, minicomputers continue to be widely used because they are generally faster and possess more capabilities.

The largest computers (“maxicomputers”) are those found in research centres, large scientific laboratories, big universities.

Most of the computer principles and concepts are common to all categories of computers, although there can be tremendous variations from computer to computer.

A question sometimes arises whether computers are able to think. As a matter of fact they do not think. The computer programmer provides a programme of instructions and data which specifies every detail of what to do, how to do, and when to do it. The computer is simply a high-speed machine which can manipulate data, solve problems, and make decisions, all under the control of the programme. If the programmer makes a mistake in the programme or puts in the wrong data, the computer will produce wrong results.

Every computer contains five essential elements or units: the arithmetic logic unit, the memory unit, the control unit, the input unit, and the output unit.

The arithmetic logic unit is the area of the computer in which arithmetic and logic operations are performed on data.

The memory unit stores groups of binary digits (words) that can represent instructions (programme) which the computer is to perform and the data that are to be operated on by the programme. The input unit consists of all the devices used to take information and data that are external to the computer and put it into the memory unit.

The output unit consists of the devices used to transfer data and information from the computer to the outside world.

The control unit directs the operation of all the other units by providing timing and control signals. This unit contains logic and timing circuits that generate the signal necessary to execute each instruction in a programme.
