Let's find out Bit (Computing) meaning, definition in crypto, what is Bit (Computing), and all other detailed facts.

In computing, a bit represents a basic unit of information. It is a contraction of the words “binary digit”. A bit represents a logical state with one of two possible values, 0 and 1.

Bits can be grouped into bytes, bit multiples that are used to store data and execute commands. One byte consists of eight bits. Four bits make up a unit known as a nibble. Information is normally processed on the byte level at the minimum. One byte can store one ASCII character.

A larger multiple, containing 1,024 bytes, is called a kilobyte. Computers use binary math, also known as the base two system, rather than decimal math. Larger units are megabytes, containing 1,048,576 bytes, and gigabytes that consist of 1,073,741,824 bytes. Some devices measure memory in terabytes or 1,099,511,627,776 bytes.

For the sake of simplicity, some hard drive manufacturers use the decimal system to define the storage space of their devices. In this case, 1 megabyte is defined as equal to one million bytes.
