What is the C.P.U?

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified by the instructions.

Where is the C.P.U located?

The CPU is generally a two-inch ceramic square with a silicon chip located inside. The chip is usually about the size of a thumbnail. The CPU fits into the motherboard's CPU socket, which is covered by the heat sink, an object that absorbs heat from the CPU.

What is RAM?

Random-access memory (RAM) is a form of computer data storage. A random-access memory device allows data to be read and written in roughly the same amount of time regardless of the order in which data items are accessed.

Where is RAM located?

RAM is located next to the processor, in clips that are about 5 inches long and the RAM just snaps into these slots.

Video - What Does Memory (RAM) Do?


A computer needs all the components to work properly for example the CPU is responsible for executing a sequence of stored instructions called a program. This program will take inputs from an input device, process the input in some way and output the results to an output device. If the computer didn't have the cpu it wouldn't be able to work.


What is the motherboard?

A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other expandable systems. It holds many of the crucial electronic components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard contains significant sub-systems such as the processor and other components.
