OUTPUT UNIT OF A COMPUTER

The work of an output unit of a computer is just the reverse of that of an input unit of a computer. It supplies information and result of computation to the outside of world. Thus it links the computer with the external environment. As computers work with the binary code, the result produced are also in the binary form. Hence, before supplying the results to the outside world, it must be converted to human acceptable (readable) form. This task is accomplished by units called output interfaces. Output interfaces of a computer are designed to match the unique physical or electrical characteristic of output devices (terminals, printer, etc.) to requirement of the external environment.

FUNCTIONS PROVIDED BY AN OUTPUT UNIT

  • It accepts the result produced by the computer which are in coded from and hence cannot be easily understood by us.
  • It converts these code results to human acceptable form.
  • It supplies the converted results to the outside world.
Examples of output unit are monitor, printer, etc.
