The Motherboard

The motherboard is the main circuit in a confusing electronic system, like a computer. All of the different parts of the computer are connected to the motherboard. This lets them work together all leading up to the main part - the motherboard. In most computers, the motherboard is a big green board, but many come in different colours like black, red and yellow to make it obvious so if it needs replacing you know what to remove or replace. The motherboard has many main parts to it for eg : CPU, Clock generator, memory controller, another controller hub but for data and USB as it is connected to the USB slot, output connecter to connect to the mouse keyboard, graphic card slots, PCI slots, flash ROMS.


A central processing unit (CPU) is like the brain of almost every computer its is often called the brain sending messages and signals to the rest of the computer to control the computer it is also the boss of the computer because without the CPU the rest of the computer is pointless. It is also one of the main parts to the motherboard.


Random access memory (or simply RAMs) is the memory or information storage in a computer that is used to store running programmes and data for the programs. Data in the RAM can be read and written quickly in any order. Normally, the random access memory is in the form of computer chips.
