| The name of a number system made up of only two digits, usually 0 and 1. Any number can be represented in the binary system, although larger numbers are much longer than when expressed in the more familiar decimal system, which uses 10 digits (0 to 9). Computers use the binary system extensively to store, receive, and transmit data. The number "1" in binary is written as 1. The number "2" is written as 10, where the one is in the "twos" position and a zero is in the "ones" position. The numbers one to 10 in binary would be: 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010. If a set of letters is numbered, letters also can be stored in binary format. |
