Number Systems

The system of numbers used by most people is the decimal system. This system is a base-ten system; that is, ten symbols (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) are used in this system. These ten symbols are called digits.

Do you know about other computer-based systems that are also in use?

They are Binary, Octal, and Hexadecimal systems as shown in Table 3.2.
