    Study Notes

    CPU Socket

    • The CPU (Central Processing Unit) serves as the brain of the computer, responsible for executing program instructions and performing calculations.
    • CPU socket types include LGA (Land Grid Array) with pins on the socket and PGA (Pin Grid Array) with pins on the CPU.

    Memory Slot

    • RAM slots allow for the insertion of RAM modules, with high-tier motherboards supporting multiple slots.
    • Variations in RAM modules include differences in pins, gaps, keyway slots, height, and length due to evolving technology.
    • Types of RAM include:
      • SDRAM: 64-bit bus, 168 pins, requires 3.3V.
      • DDR1: 184 pins, maximum capacity 1GB; compatible with various sockets.
      • DDR2: 240 pins, max capacity of 4GB, replaced DDR1 in 2005.
      • DDR3: Similar shape to DDR2, 240 pins, max capacity of 8GB; supported by LGA and AMD sockets.
      • DDR4: 288 pins, up to 16GB capacity; high-end and compatible with specific Intel and AMD sockets.

    BIOS Chip & CMOS Battery

    • BIOS (Basic Input/Output System) stores motherboard information and settings; acts as a link between hardware and software during startup.
    • BIOS resides on a ROM chip, retaining data without power.
    • CMOS battery maintains BIOS settings when the computer is powered off, prevent data loss, and is removable for resetting.

    Expansion Buses

    • Expansion buses enable the addition of expansion cards (e.g., graphics cards, sound cards) to the computer.
    • PCI (Peripheral Component Interconnect) is a common expansion bus standard, designed for connecting peripheral devices.
    • Other types of buses include ISA and EISA.

    PCI Slots

    • PCI slots accept devices requiring power; originated with Intel Pentiums in 1993.

    PCIe Slots

    • PCI Express (PCIe) superseded AGP as the mainstream connection due to enhanced transfer speeds and bandwidth, becoming standard for graphics card connections.

    IDE or SATA Slot

    • IDE (Integrated Drive Electronics) is an older interface, whereas newer motherboards utilize SATA (Serial ATA) technology for connecting storage devices, providing improved speed and efficiency.

    The Computer Chipsets

    • NorthBridge (Memory Controller): Controls data transfers between the processor and RAM, located near the CPU.
    • SouthBridge (Input/Output Controller): Manages communications with peripheral devices, including USB and audio. Known as I/O Controller Hub (ICH).
