What is Computer Hardware?

Computer hardware is the collection of physical parts of a computer system that can be touched and feel. It includes components such as the motherboard, CPU, RAM, Hard Disk Drive, SSD, GPU, Power Supply Unit (PSU), and other peripherals like a Keyboard, Mouse, and Monitor. In this note, we will go through the different computer hardware components in detail.

Major parts of a computer:

a) Input Devices:

• Keyboard: Used for typing and entering commands.
• Mouse: Used for navigating the computer screen and selecting options.

b) Output Devices:

• Monitor: displays the computer screen.

c) Cabinet Box:

• Case Body: This is the outer shell of the computer case that houses all the internal components.
• Power Supply Unit (PSU): This supplies power to all the components in the computer.
• Motherboard: This is the main circuit board that connects all the components together.
• Central Processing Unit (CPU): This is the "brain" of the computer that carries out instructions and performs calculations.
• Random Access Memory (RAM): This is the temporary memory that the computer uses to store data and instructions that are currently being processed.
• Cooling System: a fan or liquid cooling system to prevent overheating.

d) Storage Device

• Hard Disk Drive (HDD) or Solid-State Drive (SSD): This is the permanent storage device that stores all the data, files, and software programs.

These are the major parts of a computer, and they work together to perform various tasks and run software programs. Other components, such as sound cards, expansion cards, and peripheral devices, can be added to the computer to enhance its capabilities.
