To send information down wires it has to be in the form of pulses that are either in one state or another so this requires any data to be sent to be first converted into in bits, effectively rows of 1's and 0's.

Sometimes with data standards these bits can be called upon to act alone representing data in their own right for example - if a variable can only either be in one state or another, there are only 2 options so one bit in the right place on a data stream can represent this data as either 1 to represent one state and a zero to represent another.

However more complex data is sent as groups of bits called bytes and these can be used to form binary numbers. Binary numbers are very long, so there is a short hand form known as Hexadecimal.

In this section you will learn how to convert Binary, to Decimal, and Binary to Hexadecimal, and back again!
