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