    • Several motherboard sizes and types exist, including ATX, Mini-ITX, and others.
    • ATX motherboards have been popular for desktop computers since 1995.
    • Mini-ITX motherboards are suitable for small form factor computers and have limited real estate for expansion slots.

    Expansion Interfaces

    • Older computers may have different expansion interfaces, such as PCI slots, while newer ones may have PCI Express slots.
    • PCI Express buses use a serial communication path.
    • Adding more lanes to a PCI Express bus supports higher bandwidth and speed.

    Motherboard Families

    • The two main motherboard families focused on in CompTIA exam objectives are ATX and ITX.
    • ATX motherboards are commonly found in desktop computers.
    • Mini-ITX motherboards are suitable for small form factor computers.

    Power Connectors

    • The standard power connector size for an ATX motherboard is 24-pin.
    • Modular power supply connectors are used to provide power to components.
    • Keyed connectors ensure proper insertion of motherboard power connectors.

    BIOS and UEFI

    • The Basic Input Output System (BIOS) initializes the memory and CPU during the startup process.
    • UEFI (Unified Extensible Firmware Interface) is a firmware interface that replaces the traditional BIOS.
    • UEFI drivers are used to manage hardware components.

    CPU and Motherboard Compatibility

    • CPUs are designed to throttle when the system overheats, especially in laptops.
    • Laptop motherboards are designed for power usage and efficiency, not speed.
    • It is challenging to replace individual components like memory or CPU in laptops compared to desktops.

    M.2 Connectors and SSDs

    • M.2 connectors are used to connect SSDs to the motherboard.
    • M.2 connectors secure the SSD to the motherboard using a screw or clip.

    CPU Architecture and Installation

    • 64-bit processors differ from 32-bit processors in terms of data access.
    • The primary function of a CPU is to execute instructions.
    • CPU caches improve performance by reducing memory access time.

    Virtualization and Hyper-Threading

    • Hyper-Threading Technology allows a single CPU core to appear as multiple CPU cores.
    • Virtualization allows running multiple operating systems on a single physical machine.

    Graphics and Sound Cards

    • Discrete graphics cards are separate from integrated graphics in CPUs.
    • Capture cards are used to capture video input.
    • Sound cards are used for high-end audio output capabilities.

    Cooling Systems

    • Heat sinks are used to cool components in a computer system.
    • Passive cooling systems do not use fans.
    • Fans are used to provide cooling for computer systems.

    Networking and Expansion Slots

    • Expansion slots allow adding new hardware components to a computer.
    • Network Interface Cards (NICs) are used to add network capabilities to a computer.
    • Video capture cards support various video inputs.
