Components of a Desktop Computer (VDU)

It is an output device connected to a computer which displays the desired graphics output produced by the graphics processing unit of the computer. Generally known as a monitor, a computer display can be an LCD (Liquid Crystal Display) based or LED (Light Emitting Diode) based. Earlier computer display monitors were based on Cathode Ray Tube (CRT) but these became obsolete as more compact and advanced LCD and LED panels gained popularity.

For desktop computers, the display unit remains separate than the rest of the computer components. Desktop computers are useful for long usage schedules. Having a separate monitor also makes the replacement process easier if something goes wrong with the display.

The computer can connect to the display via different connection modes like VGA, HDMI, DVI, DisplayPort, etc. Intel’s Thunderbolt offers video output as well as data transfer through the same connection interface for different devices.

For laptops and netbooks, the display unit is separate but attached to the chassis housing the computer components for the reason of making it compact. This adds to the mobility and ease offered to the user. These displays use a different type of video cable to connect to the motherboard. AIOs provide best of both worlds by providing the display and the computer components in the same body.
