Study Notes

Computer Hardware

  • Definition: Physical components of a computer system that perform specific functions.

  • Main Components:

    1. Central Processing Unit (CPU):
      • The brain of the computer that executes instructions.
      • Measured in gigahertz (GHz); higher GHz indicates faster performance.
    2. Motherboard:
      • Main circuit board housing the CPU, RAM, and other components.
      • Connects different parts of the computer.
    3. Random Access Memory (RAM):
      • Temporary storage used by the CPU to store data that is actively being used.
      • More RAM allows for better multitasking.
    4. Storage Devices:
      • Hard Disk Drive (HDD): Magnetic storage with larger capacity and slower speed.
      • Solid State Drive (SSD): Flash storage, faster access times but typically more expensive.
    5. Power Supply Unit (PSU):
      • Converts electrical power from an outlet to usable power for computer components.
    6. Graphics Processing Unit (GPU):
      • Specialized processor for rendering graphics and visual effects.
      • Critical for gaming and graphic design tasks.
    7. Cooling Systems:
      • Essential for maintaining optimal operating temperatures.
      • Includes fans and heat sinks to dissipate heat generated by components.
