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