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