Parts of the Computer and their Function

ComputerA machine that processes information and performs computation.

Major Parts of the Computer

CPURAM

Hard Drive Optical DriveMotherboard

Central Processing Unit (CPU)The central processing unit (CPU) processes all of the data that is accessed by the machine. It is a small internal piece that is located beneath the fan. Essentially, the purpose of a CPU is to process instructions through a four-part sequence of fetching, decoding, execution and write-back.

RAM

Random access memory provides a buffer between the hard drive and central processing unit. When files are requested for processing, they transfer from the hard drive to the memory.

Hard Drive

• A hard drive provides permanent storage for the operating system, programs and files on a machine. When files are saved to the hard drive, they are retained through power outages.

Optical Drive

An optical drive is any drive that reads the data through optic technology, such as a laser. These drives can read data from discs.

MotherboardThe motherboard is an underlying circuit board that holds all the computer components together. Computer components, including the CPU, RAM, hard drive and optical drives, plug into the motherboard. This allows the separate components to interact with each other to create a fully functional machine. While each computer part has a unique function, they would be utterly useless without the unifying motherboard.
