Good notes will help you organise and process data and information

Many ancient cultures developed the counting system that we use today, known as the decimal system. It allows us to use ten values and it is likely that this common approach was developed because of the fact humans have ten fingers/digits to count with. You may have also heard this system referred to as denary or base-10.

Computers obviously don't have fingers, but instead use tiny switches called transistors that allow electricity to be on or off in a circuit. These circuits are combined to represent data and the two states of on or off are represented as 1 or 0. This is known as the binary or base-2 as only two values can be used. Combinations of 1s and 0s can be used by a computer to represent any type of information (e.g. numbers, text, images, sound, program instructions).
