It is a control circuit that pull data from various parts and directs them along data busses as packets of data but also can do calculations. The CPU also uses the Ram of the PC to store data.

Motherboard: This is a printed circuit board or PCB that is the most important part of the PC, this is because every component is attached to this key part, and its size and shape determines how fast and how may additional parts the pc can house.

BIOS: Basic input/output system is a collection of software utility’s that create parts of the OS system. This usually takes the form of a ROM chip that comes with the PC called a ROM BIOS. But what does the BIOS actually do? The BIOS allows the computer to boot up and allows it to configurator data, as well as check to see if hardware is working properly. The BIOS also allows the OS to use some specific features and handles input and output from the PC. The BIOS will never disappear in the event of a power failure because it is stored on the ROM.

Hard drive configuration and controllers: the hard drive is where all saved data from the user is stored on a disc. A hard disc drive are IDE devices controlled by an IDE controller, which there are two kinds; primary, this is where the HDD is normally attached and secondary where a CD/DVD drive is normally attached.
