Answer 2

Answer:

The output unit is formed by the output devices attached to the computer. The output coming from the CPU is in the form of electronic binary signals which needs to be converted in some form which can easily be understood by human beings i.e., characters, graphical or audio visual form. This function of conversion is performed by the output units.

Some popular output devices are :

• Monitors -  Monitor (or screen) is the most common form of output from a computer. It displays information in a similar way to that shown on a television screen. The picture on a monitor is made up of thousand of tiny colored dots called pixels. For visually challenged people, Braille monitors are also available.
• Printers - Printers are the devices that deliver information by means of printed characters on paper. Printers come in variety of forms, e.g., inkjet, LaserJet, dotmatrix, etc. Unlike old style printers, which printed on a paper, these days 3-d printers are also available which can print/create 3-d models.
• Speakers - Speakers receive the sound in the form of electric current from the sound card and then convert it to sound format audible to user.
