About these units
Byte (B)
- Definition
- A byte (B) is a unit of digital information made up of 8 bits, enough to store a single character.
- History
- The term was coined at IBM in the 1950s; the 8-bit byte became standard with early microprocessors.
- Current use
- Bytes are the fundamental unit for file sizes and memory in computing.
Bit (bit)
- Definition
- A bit is the smallest unit of digital information, representing a single 0 or 1.
- History
- The concept was formalised by Claude Shannon in 1948 as the basic unit of information.
- Current use
- Bits underpin all digital data; network speeds are measured in bits per second.
