A single bit is the smallest element of digital data, representing a binary state (i.e., two states), either 0 or 1. Computers process and store information using binary signals that indicate the on or off state of the binary element and are responsible for everything from text to video, with larger data units such as nibbles (4 bits) and bytes (8 bits) being used to group data into meaningful units but the basic element of all data in computing remains the bit (i.e., binary digit).
