Internal Features of the CPU and Their Uses

1. Motherboard:
   • The main circuit board that holds and allows communication between many of the crucial electronic components.
2. Processor (CPU):
   • The brain of the computer that performs instructions defined by software.
3. BIOS Battery:
   • Provides power to the BIOS firmware to maintain system settings.
4. Fan:
   • Keeps the CPU cool by dissipating heat generated during operation.
5. RAM Slot:
   • Holds the RAM (Random Access Memory) modules that provide space for the computer to read and write data.
6. Hard Drive:
   • Stores all data and information permanently.
7. Power Supply Unit (PSU):
   • Converts electrical power from an outlet into usable power for the computer components.
