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PCI Express (PCIe) superseded AGP as the mainstream connection due to enhanced transfer speeds and bandwidth, becoming standard for graphics card connections.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