What is a character?

What will be an ideal response?

A character is any one of the letters, numbers, or other special symbols (such as punctuation marks) that comprise data. Characters are made up of bits (the zeros and ones that represent computer circuitry), but people who use data do not care whether the internal representation for an 'A' is 01000001 or 10111110; rather, they are concerned with the meaning of 'A'-for example, it might represent a grade in a course, a person's initial, or a company code.
