    Study Notes

    Computer Components

    • A motherboard is a large circuit board that contains essential parts of a computer, including the CPU, RAM, and more.
    • The CPU (Central Processing Unit) is the "brain" of the computer, processing information and executing commands.
    • The CPU is covered by a heat sink, a metal piece that draws heat away from the processor to prevent overheating.

    Memory and Storage

    • RAM (Random Access Memory) is short-term memory used for calculations, but it's cleared when the computer is shut off.
    • The hard drive provides long-term storage, keeping data even when the computer is turned off.
    • Hard drives use magnetic platters to store data, but Solid State Drives (SSDs) are faster, more durable, and more expensive alternatives.

    Expansion and Upgrades

    • Desktop computers have expansion slots on the motherboard, allowing for upgrades with expansion cards.
    • Expansion cards can add features like better graphics performance (video card) or wireless connectivity (wireless card).
    • Laptops typically do not have expansion slots.

    Power Supply

    • The Power Supply Unit (PSU) takes power from the wall outlet and distributes it to various components.
    • Laptops have a built-in battery, allowing for portable use.

    Motherboard

    • Large circuit board containing essential computer parts, including CPU, RAM, and more.

    CPU (Central Processing Unit)
