A motherboard is a circuit board designed to connect the hardware pieces of the computer into a central location, allowing easy data transfer between the different components.
A motherboard has spots for RAM, a CPU, a GPU, SSDs and many different connectors.
A motherboard will use its already inbuilt connections between different hardware locations to provide an easy and fast data transfer between the different components. It can hold and distribute the necessary signals between the components, as well as allowing the addition of peripherals such as mice and keyboards to interact with the PC.
Like many components, a motherboard is quite easy to come by, however, different motherboards offer different connections, and finding the right motherboard that is compatible with your components can be tricky. However, when buying a motherboard, it will gnerally list the CPUs that are compatible with that specific motherboard. I suggest looking at this list after selecting a CPU to see if your chosen board is compatible.
