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