Visual Display Unit (VDU)

The computer can output the information by transmitting the electronic pulse code of characters through a cable to the Visual Display Unit (VDU).

The VDU decodes the transmission and displays the appropriate characters on the screen.

Most VDUs can receive and display data at speeds upto about 900 characters per second.

Latest VDUs are equipped with touch sensitivity.

There are graphical VDUs with a colour system and can produce designs which are helpful in several applications.

Most of our TV sets can be used as visual display units.

CPU can be attached to this TV set, which will act as a computer.
