The motherboard is the major circuit board that connects and allows various parts of a computer to interface with each other. It houses key components like the CPU, memory, storage devices, and other peripherals, linked using buses and pathways. Other items contained include the chipset, which helps in managing the flow of data between the CPU and the memory and peripheral devices. In addition, it provides various inputs/outputs for ports and expansion slots to accommodate the inclusion of added components, such as graphics cards or further storage.

The motherboard also plays some major roles such as supplying power to the system’s components; for example, the motherboard distributes the electrical power from the PSU to various key components that are responsible for having the system work appropriately. Motherboards are also tasked with the management of BIOS/UEFI of a system: a set of firmware interfaces that initialize hardware on system boot, providing runtime services for operating systems and programs (Soper, 2020).

Generally, the CPU is considered the “brain” of the computer because it lies at the very heart of the operation when it comes to executing instructions and processing data. The central role of a CPU involves arithmetic performance and controlling the data through fetching, decoding, execution, and writing back in a sequence normally referred to as the instruction cycle. Most modern CPUs are multi-core processors. They contain a few processing units, also called cores, which enable them to execute several tasks at a time and, thus, increase performance and efficiency.

It uses the buses on the motherboard to communicate with other parts of the system, retrieving data from memory or storage to process. In almost every aspect, it controls literally every other piece of the system, carrying out decisions based on the data fed into it, controlling operations in an efficient and smooth manner. The speed at which this occurs, usually measured in gigahertz, determines the clock speed of the CPU.
