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  • PCI Express (PCIe) superseded AGP as the mainstream connection due to enhanced transfer speeds and bandwidth, becoming standard for graphics card connections.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