A bit (short for “binary digit”) is the basic unit of information in computing and represents a single digit in a binary number. A binary number is a number represented using only two digits: 0 and 1. Each digit in a binary number is called a bit.
In computer systems, bits are used to store and process information. They can be used to represent a wide range of data types, including numbers, text, images, and other types of data.
Bits are often grouped together to form larger units of information, such as bytes (which are typically made up of 8 bits), words (which are typically made up of several bytes), and larger units such as kilobytes, megabytes, and gigabytes.
Overall, bits are the fundamental unit of information in computing, and are used to store and process all types of digital data.
