The chapter objectives are to explain key components and functions of the motherboard, including data buses, processors, cache memory, chipsets, cooling systems, and expansion slots. It also covers installing processors, overclocking, throttling, and troubleshooting motherboards. The document provides definitions of technical terms and describes how different components work together to process data in a computer system.

9. How data is transferred E.g. Dear Mom 8-bit CPU – One letter at a time 16-bit CPU – Two letters at a time 32-bit CPU – Four letters at a time 64–bit CPU – Eight letters at a time

10. Multi-core Processors Combines two processors in a single unit . Dual-core CPU Tri-core CPU Quad-core CPU Combines three processors in a single unit. Two dual-core processors on the same motherboard or two dual-core processors installed in a single unit. Another way to speed up operations is to have two or more processors.

11. Cache Cache memory that is located inside the CPU. L1 (Level one) cache L2 cache Cache memory that is inside the CPU housing but not part of the CPU, also known as on-die cache . Cache memory located in the CPU housing or on the motherboard. L3 cache Cache - A fast type of memory designed to increase the speed of microprocessor operations.

23. Installing Processors Computer is off and unplugged. Use antistatic wrist strap and attach to a ground on computer. Remove old processor by lifting ZIF socket retaining lever. Insert CPU into socket (fits only one way). Configure motherboard by jumpers or BIOS software configuration (refer to manual for exact steps). Always hold the CPU by the edges to avoid bending or touching the pins underneath.

24. Overclocking Processors In order to overclock, you must have the motherboard documentation to determine whether the system board supports different CPU speeds and different multipliers. Overclocking Is changing the front side bus speed and/or multiplier to boost CPU and system speed. This can cause damage to the CPU, motherboard, or other components.
