    • Cache memory is fast, built into the processor, and stores often-used data.
    • Read Only Memory (ROM) is permanent, holds startup instructions, and can't be written to.
    • Secondary memory (like hard disk drives, flash drives, and SD cards) stores long-term data.
    • Primary memory is faster than secondary memory for accessing data;

    Communication Devices

    • Communication devices handle data transfer between devices.
    • Networks are connections between hardware; the network allows sharing of software and data.
    • Network cards (NICs) allow computers to connect to a network.
    • Common examples include Bluetooth, network cards, routers, and repeaters.

    Computer Motherboard

    • The motherboard is the main printed circuit board within the computer.
    • It houses essential components like the CPU, memory slots, expansion slots, BIOS chip, and CMOS battery.

    Expansion Slots

    • Expansion slots connect various devices to expand the computer's functionality.
    • Common slots are PCI, AGP (replaced by PCIe), and PCIe slots.

    PCI Slots

    • PCI slots are white, about 3 inches long.
    • They are used to add devices like graphic cards, sound cards, network cards, wireless cards, and USB expansion cards.

    AGP and PCIe Slots

    • AGP is a high-speed point-to-point channel for 3D graphics cards, but is now replaced by PCIe.
    • PCIe is a quicker slot that improves data transfer speed and reduces latency.

    Types of Computers

    • Personal computers (PCs) are commonly used by one person.
    • Organizational computers are used by multiple people.
      • Minicomputers or midrange servers are for smaller companies.
      • Mainframes are powerful machines to process business data for multiple clients.
      • Supercomputers handle extremely large scientific calculations.

    System Software

    • System software enables hardware components to work together smoothly.
      • Operating systems (like Windows, macOS, Linux) coordinate hardware and application interactions.
      • System utilities (like antivirus programs, file managers, and backup software) perform maintenance and special tasks.

    Computer Motherboard: Other Components

    • The BIOS (Basic Input/Output System) is a non-volatile ROM chip for startup instructions.
    • The CMOS (Complementary Metal-Oxide-Semiconductor) chip stores settings like date and time, even when powered off.
