- A digital computer is one that directly counts number or digits that represents number, letter or other special symbols.
- It is a computer capable of solving problems by processing information in discrete form. It is operated on data, including magnitudes, letters, and symbols, that are expressed in binary form.

- A Digital Computer works with digits to represent numerals, letters or other special symbols. Digital Computers operate on inputs which are ON-OFF type and its output is also in the form of ON-OFF signal. Normally, an ON is represented by a 1 and an OFF is represented by a 0. So we can say that digital computers process information which is based on the presence or the absence of an electrical charge or we prefer to say a binary 1 or 0.
