CIT120 Chapter 2 Digital data representation All digital devices work in two states. Circuits, for example, be open or closed, current flows in one direction along a wire or the other, and so forth. The two states of a digital computer atomic number 18 typically be by 0s and 1s, which are referred to as bits (Binary digits) . Since computers are digital, they have to accomplish all computations using 1s and 0s, so the double star add up system is used for mathematical computations. Example 7 0000 0111 +4 0000 0100 11 0000 1011 The ASCII and EBCDIC codes represent one source with 8 bits (one byte). The or so common byte abbreviations (such as KB, MB, and GB); see this table: abridgment tot of bytes approx.

To provide for to a greater extent needful characters, the Unicode character narrow down is being used, which provides for a character set of 65.536 different characters. All data (including numbers, letters, images, video, audio, etc.) must be delineate by 0s and 1s. All programs must be reborn in a binary equivalent (machine language) before execution.
