What is a Motherboard?

The motherboard, also called the mainboard, is the main circuit board of a computer. Every other component connects to it.

What the Motherboard Does

The motherboard allows the CPU, RAM, storage and other devices to communicate. It provides power and data pathways between every part of the system.

Key Components

• CPU socket: Where the processor is installed.
• RAM slots: Where memory modules fit.
• Chipset: Manages communication between components.
• Expansion slots: For graphics cards and other add-ons.
• Ports: USB, HDMI, audio and network connections.

Why It Matters

The motherboard decides what parts a computer can use. When building or upgrading a PC, choosing the right motherboard is essential.
