But this type of data is not suitable for computers. Computers only understand the numbers. So, when we enter data, the data is converted into electronic pulse. Each pulse is identified as code and the code is converted into numeric format by ASCII. It gives each number, character and symbol a numeric value (number) that a computer understands.  So to understand the language of computers, one must be familiar with the number systems.
