A bit is a binary digit and is the nominal unit of data in a computer. Bits can just have one of two statuses, moreover on or off. These two status stand for the two principles a bit can have, either 1 or 0. A byte is set of 8 bits.

All is stored as well as calculated in computer by utilizing this two value number in the system, which are also called as binary code or the system language. All storage and calculation process in a computer are done by using this binary calculation.

The basis there are merely two conditions for a bit is because of the temperament of transistors, which are the building chunk for all digital electronic circuit. For scientific basis beyond the extent of this conversation, transistors used in digital circuits can be in only one of two steady statuses, whichever completely on or completely off.

In difference, the number system we utilize every day is decimal and it has ten states or values. The decimal digits are like 0, 1, 2,3,4,5,6,7,8 and 9 stands for the ten principles a number can enclose.
