What is the Motherboard?

The motherboard is a thin plate in a desktop computer. It connects either directly or indirectly to every part of the computer.

What is the CPU?

The computer processing unit is located inside the computer case on the motherboard. It is sometimes called the brain of the computer and its job is to carry out commands.

It is protected by the heat sink, that stops the CPU from getting too hot.

What is the RAM?

The random access memory is your system's short term memory. Whenever your computer performs calculations, it temporarily stores the data in the RAM until it is needed.

What is the Hard Drive?

The hard drive is where your software, documents and other files are stored. The hard drive is long term storage, which means the data is still saved even if the computer has been turned off or unplugged.

What is the Power Supply?

The power supply unit in a computer converts the power from the wall outlet to the type of power needed by the computer. It sends power through cables to the motherboard and other components.
