Next in line to the Motherboard and equally important is the CPU.
CPU stands for Central Processing Unit, a programmable logic device that
performs all the instruction, logic, and mathematical processing in a computer.
The CPU is the 'brain' of the computer. Also referred to as the processor
or central processor.
In terms of computing power, the CPU is the most important element of a computer
system. On large machines, CPUs require one or more printed circuit boards.
On personal computers and small workstations, the CPU is housed in a single
chip called a microprocessor.
The CPU is about quarter of an inch in width with pins underneath it. It is usually black or dark grey. The CPU will likely be the larger of the chips on the motherboard inside your PC.
