ASCII:

A code where each number represents a character can be used to convert text into binary. One code we can use for this is called ASCII. The ASCII code takes each character on the keyboard and assigns it a binary number. For example:

the letter ‘a’ has the binary number 0110 0001 (this is the denary number 97)

the letter ‘b’ has the binary number 0110 0010 (this is the denary number 98)

the letter ‘c’ has the binary number 0110 0011 (this is the denary number 99)
