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