Cache memory: Cache memory is fast memory that is used as a data buffer it buffers data between the CPU and RAM. Cache memory acts as a buffer, holds data the CPU will need, like things that are used a lot. Cache memory makes up for the mismatch of speed between the CPU and RAM. BIOS: Bios stands for (Basic Input Output System) it is a collection of software utilities that form part of the operation system.

Also a motherboard has a North bridge and South Bridge. The Northbridge is for fast CPU, memory and graphics mostly used for multimedia and gaming. The South Bridge is slower than the North Bridge and used in a lower end PC, Also a Motherboard can require cooling. CPU: A CPU is the central processing unit what controls the whole computer; The CPU has 2 major manufactures AMD or Intel. Also the CPU can have multiple cores instead of one, some CPU’s require...
