The three basic tasks a computer system preforms are super simple. Number 1, data is entered into the computer by an input device(mouse or keyboard). Number 2, data is processed to obtain the results, or travels into the CPU and the motherboard. Number 3, the results are outputted by an output device(printer), or stored in a storage device (pin-drive).

  Input devices really help us use the computer better, for example, a mouse or a keyboard. Output devices help us take information out from the computer, for example, pin-drives and USB connection. CPUs (central processing units) are what most people call the brain of the computer. Motherboards is a circuit board that contains the principal components or parts of a microcomputer or other device. Other circuit can be connected or slotted.
