List the seven basic internal components found in a computer tower

These are :

1. Central Processing Unit (CPU). This is the brain of the computer and performs the basic logical, arithmetic , input & output operations of the computer system.

2. RAM. This is Random Access Memory. It is used by the CPU when the computer system is running to temporarily store information which needs to be used quickly and  which would otherwise be lost when there is no power.

3. Motherboard. This is a crucial  part that holds together the  critical components of a computer including the CPU, memory and input/output connectors.

4.Hard drive. This is the component that stores data permanently.

5. Power supply unit. This is  a component that converts mains AC power to DC power for use by the internal parts of the computer.

6. Cooling system. This consists mainly of fans attached to computer enclosures that maintain inflow of cool air and expelling of hot air out of the computer tower.

7. Frame. This is the hard casing that houses  the computer parts protecting them and keeping them together.
