Computer

Computer is an electronic device that can receive a program (a set of instructions) and then carry out this program. The most important parts of the computer are as follows: 1) memory, it keeps information; 2) an arithmetic unit that performs calculations; 3) a control unit, it checks the correct order of operations; 4) input devices; 5) output devices, they display the results of calculations. The input and output devices are called peripherals.

Memory is the system of the component of the computer in which it stores information. There are two types of computer memory: RAM and ROM.

RAM (random access memory) is the volatile computer memory. Computer uses it for creation, load and run programs and for manipulations and storage of the data.

ROM (read only memory) is non-volatile and unchangeable computer memory. Computer uses it to hold programmed instructions to the system.

The more memory you have in your computer, the more operations you can perform.

TASK: Read and translate this text. Find in the text the words from vocabulary and give the synonyms. Learn the vocabulary by heart.

Computer, machine that performs tasks, such as mathematical calculations or electronic communication, under the control of a set of instructions called a program. Programs usually reside within the computer and are retrieved and processed by the computer's electronics, and the program results are stored or routed to output devices, such as video display monitors or printers. Computers are used to perform a wide variety of activities with reliability, accuracy, and speed. (475)

TEXT № 2 . USES OF COMPUTERS

TASK: Read and translate the following text. Point out the main idea. Can you add something else about the computer usage? Learn the vocabulary by heart.

People use computers in a wide variety of ways. In business, computers track inventories with bar codes and scanners, check the credit status of customers, and transfer funds electronically. In homes, tiny computers embedded in the electronic circuitry of most appliances control the indoor temperature, operate home security systems, tell the time_, and turn videocassette recorders on and off. Computers in automobiles regulate the flow of fuel, thereby increasing gas mileage. Computers —-also entertain, creating digitized sound on stereo systems or computer-animated features from a digitally encoded laser disc. Computer programs, or applications, exist to aid every level of education, from programs that teach simple addition or sentence construction to programs that teach advanced calculus. Educators use computers to track grades and prepare notes; with computer-controlled projection units, they can add graphics, sound, and animation to their lectures (see Computer-Aided Instruction). Computers are used extensively in scientific research to solve mathematical problems, display complicated data, or model systems that are too costly or impractical to build, such as testing the air flow around the next generation of space shuttles. The military employs computers in sophisticated communications to encode and unscramble messages, and to keep track of personnel and supplies. (1389)
