Study Notes

Motherboard and CPU Overview

The main function of a motherboard in a computer system is to connect and support all hardware components together.

Motherboard Sub-Systems

A motherboard typically has several significant sub-systems, including the chipset, memory (RAM), storage (hard drive or SSD), and input/output (I/O) systems.

Central Processing Unit (CPU)

The Central Processing Unit (CPU) is commonly referred to as the "brain" of the computer.

CPU Speed

The speed of a computer is determined by the clock speed of the CPU, measured in hertz (Hz) or gigahertz (GHz).

CPU Components and Functions

The three main components of a CPU are:
- Control Unit: retrieves and decodes instructions, generates control signals to execute instructions.
- Arithmetic Logic Unit (ALU): performs mathematical operations and logical comparisons.
- Registers: small amount of on-chip memory that stores data temporarily while it is being processed.
