## Full Form of BIT:

### Binary Digit

* BIT Full Form* is

**Binary Digit**. BIT is an elementary unit of information used in digital communications and computing. A BIT can only comprise 2 values and may be physically incorporated in a two-state device. These values are usually represented as 1 or 0. In terms of information theory, the BIT is regarded as equivalent to

*Shannon*unit. The two values mentioned before can be interpreted as algebraic signs, logical values, activation states, or other two-valued attributes. The correspondence between the physical states and the aforementioned values is a matter of use and convention.

A binary number’s length is often referred in terms of bit-length. As far as Information Theory is concerned, one bit is usually characterized as the uncertainty that exists in a binary random variable or the information which is acquired when the value of such random variable eventually becomes known. In quantum computing, qubit or quantum bit is essentially a quantum system existing in what is called the superposition of 2 classical or non-quantum bit values.

The symbol used to represent a bit is simply bit or *b. *The term byte is used to refer to a group comprising 8 bits, though there is no strict definition of the size of a byte. Apart from bits, there are other units of information used such as the natural digit which is represented by *nit*or *nat*; the *ban, dit, *or *Hartley. * These are, however, not as rampantly used as bits, which is a more acceptable unit of information used in digital communications and computing.
