Data representationBITShort for binary digit, the smallest unit of information on a machine. The term was first used in 1946 by John Tukey, a leading statistician and adviser to five presidents. A single bit can hold only one of two values: 0 or 1. More meaningful information is obtained by combining consecutive bits into larger units. For example, a byte is composed of 8 consecutive bits.Transmission and processing

Bits can be implemented in many forms. In most modern computing devices, a bit is usually represented by an electrical voltage or current pulse, or by the electrical state of a flip-flop circuit.For example, in transistortransistor logic (TTL) and compatible circuits, digit values 0 and 1 at the output of a device are represented by no higher than 0.4 volts and no lower than 2.6 volts, respectively; while TTL inputs are specified to recognize 0.8 volts or below as 0 and 2.2 volts or above as 1.

BYTE Byte is a unit of digital information in computing and telecommunications that most commonly consists of eight bits. 1000 bytes = 1 kilobyte1000 kb = 1 megabyte1000 mb = 1 gigabyte1000 gb = 1 terabyte1000 tb = 1 petabyte
