Recap:What is Binary?
In computing, we often use two systems to represent numbers: binary and denary.
The binary system uses only two digits, 0 and 1 because computers only understand this.
While the denary system is the one we use every day, which includes the digits from 0 to 9.
In denary, a number is represented with Units, Tens, hundreds, thousands (Goes up by x10)
In binary, a number is represented with 1, 2, 4, 8, 16 .... (goes up by x2)
e.g. 128 64 32 16 8 4 2 1
Each Binary digit, is called a "bit".
E.g. The denary number 64 can be represented in binary (0s and 1s) as 01000000.
