Understanding the C.P.U
How Does C.P.U Work ???
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.
