# What is Bit?

A bit is a basic unit of information or is the smallest unit of data in the computer and digital communications, which stands for binary digit. Either 1 or a 0 (off or on, low or high, false or true) is used to represent each bit. A byte is made up of eight bits, if you had three bytes (word), it would be 24 bits (3 x 8=24), and 12 bytes will be 96 bits (12 x 8=96).

Usually, computers offer instructions that can manipulate and test bits, but they are designed to store collected data in an eight-bit piece known as bytes. The four bits (half a byte) are known as a nibble. For an eight-bit unit, rather than byte the term octet is used in some computers. The octets or four eight-bit bytes form a 32-bit word on many computers. In such systems, the length of instructions is sometimes explicated as half-word (16 bits in length) or full-word (32 bits in length).

There are many other forms that can be used to represent bits; those various forms are electrical voltage, through current pulses, or the state of an electronic flip-flop circuit. Most of the logic devices represent the binary digit 0 as a logical false value and 1 for true. Through voltage levels, the difference between them is stated. Generally, the bit is how the information is transmitted and expressed in computing.

Also, with the help of bits, the computer’s processing power may be measured in terms of how many bits can be processed by a computer at one time. The number of bits is used in graphics; each dot reflects the color, quality, and clarity of the picture. Furthermore, the number of bits per second communicated over a network. Byte, which is correspondent to one alphanumeric character and comprises eight consecutives; also, it is the most common storage unit in a computer. The components of computer storage, like files, disks, and databases, contain storage capacities expressed in bytes instead of bits.
