What is inside a computer?

Computers are made up of components(parts)! What are those parts you ask? take a look below

CPU(Central Processing Unit)

The CPU is the “brains” of the computer. The central processing unit does all the calculations and handles all of data. Each time the user clicks a key, opens an application or even looks at emails, the CPU reads the code involved and returns the response to the user. The CPU works closely with the rest of the components to complete a task.

RAM(Random Access Memory)

If a computer was a human, RAM would be its short term memory, The amount of RAM in a computer can vary for example most computers in 2019 will have 4GB or 8GB of RAM, When a computer is turned off, anything in the RAM is lost.

Hard Drive
