TEXT № 7. Input Devices

TASK: Read and translate the following text. Learn the vocabulary by heart.

Input devices, such as a keyboard or mouse, permit the computer user to communicate with the computer. Other input devices include a joystick, a rodlike device often used by game players; a scanner, which converts images such as photographs into binary information that the computer can manipulate; a light pen_, which can draw on_, or select objects from, a computer's video display by pressing the pen against the display's surface; a touch panel, which senses the placement of a user's finger; and a microphone, used to gather sound information. (546)

Vocabulary:

to permit – позволять

to include – включать

rodlike device – устройство в виде стержня

placement – расположение

TEXT № 8. The Central Processing Unit

TASK: Read and translate the following text. Learn the vocabulary by heart. Retell Briefly this text. Give the synonyms of the word information. Compose orally three sentences with this words.

Information from an input device or memory is communicated via the bus to the central processing unit (CPU), which is the part of the computer that translates commands and runs programs. The CPU is a microprocessor chip—that is, a single piece of silicon containing millions of electrical components. Information is stored in a CPU memory location called a register. Registers can be thought of as the CPU's tiny scratchpad, temporarily storing instructions or data. When a program is run, one register called the program counter keeps track of which program instruction comes next. The CPU's control unit coordinates and times the CPU's functions, and it retrieves the next instruction from memory.

In a typical sequence, the CPU locates the next instruction in the appropriate memory device. The instruction then travels along the bus from the computer's memory to the CPU, where it is stored in a special instruction register. Meanwhile, the program counter is incremented to prepare for the next instruction. The current instruction is analyzed by a decoder, which determines what the instruction will do. Any data the instruction needs are retrieved via the bus and placed in the CPU's registers. The CPU executes the instruction, and the results are stored in another register or copied to specific memory locations. (1321)

Vocabulary:

input device – устройство ввода

TEXT № 9. Output Devices

TASK: Read and translate the following text. Learn the vocabulary by heart. Add some information about output devices. Give the synonyms of the word monitor.

Once the CPU has executed the program instruction, the program may request that information be communicated to an output device, such as a video display monitor or a flat liquid crystal display. Other output devices are printers, overhead projectors, videocassette recorders (VCRs), and speakers. (297)
