2.2b) Name the different parts of a computer.

 A computer is composed of various parts that work together to perform its functions. These parts can be categorized into hardware and peripheral devices.

1. Internal Components (Hardware):

1. Central Processing Unit (CPU): The brain of the computer that processes instructions.
2. Motherboard: The main circuit board connecting all components of the computer.
3. Memory (RAM): Temporary storage used for active processes and data.
4. Storage Devices:
   • Hard Disk Drive (HDD) or Solid-State Drive (SSD): For long-term data storage.
5. Power Supply Unit (PSU): Converts electricity to a usable form for the computer.
6. Cooling System: Includes fans and heat sinks to prevent overheating.
7. Graphics Processing Unit (GPU): Handles image and video rendering (integrated or dedicated).
8. Network Interface Card (NIC): Enables connection to networks and the internet.
