The motherboard is the main circuit board inside a computer that connects the different parts of a computer together. It is the backbone that ties the computers components together at one spot and allows them to talk to each other. The motherboard provides a platform on which manufacturers can connect all the necessary components to ensure that the computer functions. Here are some of the functions of a motherboard:

• Acts as the central backbone of a computer on which other modular parts are installed such as the CPU, RAM, and hard disks.
• Acts as the platform on which various expansion slots are available to install other devices/interfaces.
• Distributes power to the various components of the computer.
• Coordinates the various devices in the computer and maintains an interface among them.
• Boosts the capabilities of a computer by having additional features and functionalities, such as built-in sound and video capabilities that can enhance the computers output.
• Allows users to connect peripheral devices such as printers, enabling computers to perform additional tasks such as printing documents.
• Provides a stable foundation for its components to operate, thus boosting the overall reliability of the computer.

The motherboard contains firmware, such as the BIOS, and many other components like CPU socket, RAM slots, chipset, expansion slots, SATA connectors, power connectors, BIOS chip, clock generator, USB headers, audio headers, etc. .
