Characters are represented in computers as a binary bit pattern.

Consider English alphabet A - Z
We can assign number to each character in Alphabet
Ex: A:1, B:2, C :3 .... Z:26
then ABC = 123

Write your first name here

Now write it in A:1, B:2 ... Z:26 encoding

Example ABC=123

As the computers can only store binary numbers,
we assign a decimal number to each character
and convert it to binary when storing in memory.

Write your name again
