The motherboard is mounted inside the computer case and is securely attached via small screws through pre-drilled holes. All of the components in a computer connect to the motherboard in one way or another.

  • Expansion Cards: Motherboards usually contain a number of slots for internal peripheral cards like video cards and sound cards to connect to.

  • Back Panel Connectors: The back panel connectors extend out the back of the case for connection to external peripherals.

  • CPU & Memory Sockets: The CPU and memory connect directly to the motherboard via the CPU socket connector and memory slots.

  • Storage Drive Connectors: Storage devices are connected via cables to the motherboard. There are special connectors for floppy drives, optical drives and hard drives.
