When we type some letters or words, the computer translates them in numbers as computers can understand only numbers. A computer can understand positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number.
A value of each digit in a number can be determined using
● The digit
● The position of the digit in the number
● The base of the number system (where base is defined as the total number of digits available in the number system).
