    Study Notes

    Computer Components and Connections

    • Physical connections between computer components include buses, cables, and connectors that allow data transfer and communication.
    • The Central Processing Unit (CPU) is essential for executing instructions and performing calculations in a computer.

    Basic Computer Organization

    • Three main components of basic computer organization are:
      • Central Processing Unit (CPU)
      • Memory subsystem
      • Input/Output (I/O) subsystem

    Memory Subsystem

    • The Memory subsystem is responsible for storing data and program instructions that the CPU uses during processing, allowing for quick retrieval and access.

    I/O Subsystem

    • The I/O subsystem facilitates communication between the computer and external devices, handling input from users and output to displays or printers.

    System Bus

    • The System bus serves as the communication pathway between different components of a computer, including the CPU, memory, and I/O devices, enabling data transfer and coordination.

    Data Storage for CPU

    • The cache memory, a part of the memory subsystem, is responsible for temporarily storing frequently accessed data for quick retrieval by the CPU, enhancing processing speed and efficiency.
