    • Hard Disk: Stores large amounts of data, typically inside the CPU box.
      • Size: 3.5" (desktops), 2.5" (laptops), 1.8" (portable devices).
      • Capacity: Measured in bytes.
      • Speed: Measured in transfer rate (bytes per second) and access time (milliseconds).

    Hard Disk Interface

    • Integrated Drive Electronics (IDE): Later renamed ATA and PATA.

    Networking Basics

    • Local Resources: Devices accessible only on your own computer.
    • Networking: Sharing resources among multiple computers.
