Best Answer

Usually the Central Processing unit (CPU), the drives, and the video adapter.

If you are building a PC, it would be the motherboard, case and power supply.

Another way of looking at in would be the computer, the display (LCD or CRT) and the keyboard (input device).

This question is a bit ambiguous for a single accurate answer.

graphics processing unit (video card) (gpu) you can either get ones that are integrated onto the motherboard (I wouldn't bother with integrated) or a graphics card (which are better for gaming). The two main competitors are Geforce and Radeon

motherboard (all the other components need to be compatible with the motherboard as they all get placed on it).

central processing unit (cpu) [the brains of the computer]

power supply unit (psu)

memory RAM - the more RAM you have the faster/better your computer will be able to handle multitasking i.e. running multiple programs.

HDD or SSD (more expensive for less but runs much faster than HDD) which is storage

Basically, make sure that all the acronyms match.

From a technical view the 3 very basic components which make up a computer, your looking at input, processing, & output.

Input - some sort of device which sends data and instructions to the CPU
Processing - the central processor which computes and relays back the instructions to Output
Output - a piece of hardware which receives the processed data back from the CPU


There's considered a 4th component which is storage as well, such as memory and a hard drive.
