The main circuit board inside a computer is called the motherboard (also known as the mainboard or main circuit board). It is the central printed circuit board that houses the CPU (central processing unit), memory (RAM), chipset, and other essential components. The motherboard provides the electrical connections and communication pathways between these components and supports expansion cards and peripheral connectors. It acts as the backbone of the computer, enabling all hardware parts to work together
. Key functions and features of the motherboard include:
- Hosting the CPU socket where the processor is installed.
- Providing memory slots for RAM modules.
- Containing the chipset that manages data flow between CPU, memory, and peripherals.
- Offering expansion slots for graphics cards, network cards, and other add-ons.
- Including connectors for storage devices (e.g., SATA, NVMe).
- Distributing power from the power supply to all components.
- Housing firmware chips like BIOS or UEFI for system startup
In summary, the motherboard is the primary circuit board that connects and coordinates all internal components of a computer system.
