Extensive CyberSecurity Study Guide

This study contains concepts from computer hardware to networking, etc.

Motherboard

The primary circuit board that allows hardware components to connect and communicate with each other.

PC Bus

Electrical pathways, or lines, that transfer data and instructions on a motherboard. More pathways result in higher performance.

Northbridge Chipset

Also called “Memory Controller Hub”. Connects the CPU to high speed components such as RAM, display, and high-speed PCIe expansion slots.

Southbridge Chipset

Also known as the “I/O Hub”. Links the CPU through the Northbridge to lower speed expansion slots and ports such as Ethernet, Audio, USB and SATA.

Direct Media Interface

A bus that allows communication between the CPU and the Platform Controller Hub (on modern motherboards) acting as a link between the two.

Platform Controller Hub (PCH)

Parts of the Northbridge chipset were integrated into the Southbridge chipset and renamed.
