Hardware and Software

What is Software?

Software is a collection of instructions that can be 'run' on a computer. These instructions tell the computer what to do.

Main Memory

Any data or instructions that are to be processed by the CPU must be placed into main memory (sometimes known as primary storage).

The Difference Between Hardware and Software

Computer hardware is the physical components that make up the computer system. Hardware is useless without software to run on it.

Random Access Memory (RAM)

Random Access Memory (RAM) is the part of the computer that temporarily stores the instructions that the computer is running, and the data it is processing

Central Processing Unit (CPU)

The CPU is the 'brain' of the computer. It is the device that carries out software instructions.
