Bit
The Bit is the basic unit of information in Computing and digital communications. The name is a Portmanteau of binary digit. In Information Theory, one Bit is the information capacity of a single binary random variable. The concept was pioneered by Claude Shannon in 1948. A Bit can store only one of two values, typically 0 or 1, which can represent states such as on or off, true or false, or high and low voltage in Electronic Circuits.
In most modern Computer Systems, a Bit is too small to be addressed individually; instead, data is processed in groups called Bytes. A standard Byte consists of eight bits. The Binary Number System forms the mathematical foundation for how bits represent complex data types, including integers, floating-point numbers, and characters via encoding schemes like ASCII or Unicode. Physical storage of a Bit can occur in various media, such as Magnetic Storage, Optical Discs, or Semiconductor Memory.
