Output Unit

Output unit consists of all the output devices. Those devices which help the user to get information from the computer are known as output devices. Output devices receive information from the Central Processing Unit (CPU) and present it to the user in the desired form.
An output device performs the following functions:

• Accepts results produced by the computer in binary coded form.
• Converts the binary coded data into human understandable form.
• Supplies converted results to the outside world.

There are two types of output generated by the output devices, Hardcopy Output and Softcopy Output. The output generated by the monitor is called softcopy and it exists temporarily. The output generated by the printer is called hardcopy output and it exists in a permanent form of paper.
