A binary digit. The fundamental element of computer logic and numbers. Represents one of two values: zero or one, off or on, false or true. 

Bits are needed to store and process the data in the computer. There are 32-bit and 64-bit computers with different bit sizes. The amount of bits that make the computer work faster also helps to process the data faster. Bits, consisting of strings of binary numbers, are also very important for writing code and copying data. With the developing technology, the working speed of computers with increased bits is also increasing. The faster running of the data depends entirely on the amount of bits in the computer. People who serve in the field of informatics prefer computers with high bits.
