Прочитайте текст и заполните пропуски следующими словами и словосочетаниями:The datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices of a computer is the central processing unit (CPU). In addition to
performing arithmetic and logic operations on datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices , it times and controls the rest of the system.
Mainframe and supercomputer CPUs sometimes datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices of several linked microchips,
called microprocessors, each of which datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices a separate task, but most other
computers require only a single microprocessor as a CPU.
Components known as datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices let users enter
commands, data, or programs for datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices by the CPU. Computer keyboards are
the most common input devices. Information typed at the keyboard is translated
into a series of datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices that the CPU can manipulate.
Most digital computers store information both
internally, in what is called datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices , and externally, on auxiliary datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices units. As a computer processes data and instructions, it temporarily
stores information in main memory, which consists of random-access memory
(RAM). Random access means that each byte can be stored and datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices directly, as opposed to datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices as on magnetic tape.
Components that let the user see or hear the results
of the computer’s data processing are known as datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices . The most common one
is the video display terminal (VDT), or datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices , which used a cathode-ray
tube (CRT), which is nowadays out of date, or liquid-crystal display (LCD) to
show datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices and graphics on a television-like datamonitorperformscharactersmain memoryoutput devicesheartprocessingretrievedstoragebinary numbersscreenconsistsequentiallyinput devices .
