[Tutorial ] Computer parts and what they do. [Peripheral]

Peripherals are quite simple. If you do not know what a Peripheral is they are any hardware items that are connected internally or externally to a computer and are used in data transfer for example:

*game controllers

[Tutorial ] Computer parts and what they do. [BUS]

SA collection of wires through data is transmitted from one part of a computer to another. You can think of a bus as the highway on which data travels within a computer. 

Looks like this:

    [Tutorial ] Computer parts and what they do. [Memory/ram]

    RAM stands for Random Access Memory. It is what you are actually using at any one time. Let me try to explain it this way. Your brain has a conscience and a sub-conscience memory. The conscience memory is what you are using right now. The sub-conscience memory is what you will you need to remember something that happened a long time ago [this would be the hard drive/hard disk].

    When you access your sub-conscience memory, then those memories are transferred to your conscience memory. Think of a computer in the same way. The hard drive is the sub-conscience memory, so to speak. When your computer turns on, then what it needs to run your programs is then transferred to the RAM, or conscience memory of your computer.

    When you are finished with a program or application, and you close the program, then it is wiped out of the RAM in order to make room for more applications, but it stays on your hard drive so you can recall it later. Same goes for when you turn off your computer. Eg. when you go to sleep.

    [Tutorial ] Computer parts and what they do. [Motherboard]

    A motherboard is also known as a main board, system board and logic board. Motherboards can be found in a variety of electrical devices, ranging from a TV to a computer. Generally, they will be referred to as a motherboard or a main board when associated with a complex device such as a computer, which is what we shall look at. Put simply, it is the central circuit board of your computer. It is the 'brain' of the computer. All other components and peripherals plug into it, and the job of the motherboard is to relay information between them all. Despite the fact that a better motherboard will not add to the speed of your PC, But it is important to have a motherboard that can process information fast enough to keep up with the information it is given.
