Computers store information using bits. A bit (short for "binary digit") stores either the value 0 or 1 .
A single bit can only represent two different values. That's not very much, but that's still enough to represent any two-valued state.

Computers use multiple bits to represent data that is more complex than a simple on/off value.
A sequence of two bits can represent four (22 ) distinct values:
00 , 01 , 10 , 11
A sequence of three bits can represent eight (23 ) different values:
000 , 001 , 010 , 011 , 100 , 101 , 110 , 111
A sequence can represent many things: a number, a character, a pixel. Plus, the same sequence can represent different types of data in different contexts. The sequence 1000011 could represent 67 in a calculator application while also representing the letter "C" in a text file. Learn more in our lessons on Binary numbers and Storing text in binary
Computers typically store bits using electromechanical transistors which can map electrical signals to either an on or off state. Learn more in our article From electricity to bits or this video on how transistors work.

The bit is the most basic unit of information in computing and digital communication. The name is a portmanteau of binary digit. The bit represents a logical state with one of two possible values. These values are most commonly represented as either " 1" or "0 ", but other representations such as true/false, yes/no, on/off, or +/− are also ...

A bit is always in one of two physical states, similar to an on/off light switch. The state is represented by a single binary value, usually a 0 or 1.
Oct 31, 2023 · A binary digit, or bit, is the smallest unit of information in a computer. It is used for storing information and has a value of true/false, or on/off. An individual bit has a value of either 0 or 1, which is generally used to store data and implement instructions in groups of bytes.
