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