A bit, short for binary digit, is the most basic unit of information in computing and digital communications. It can represent one of two values: 0 or 1. Bits are the building blocks of all digital data, including text, images, and videos, as they are used to encode information in a format that computers can process. In computing, bits are often grouped together to form larger units of data. For example, a byte consists of 8 bits and can represent 256 different values. This grouping allows for more complex data representation, enabling the storage and transmission of information in various formats, such as text, images, and audio.
