digital information
Quick Summary
Digital information is data represented in a two-state, or binary, form, meaning it exists as the presence or absence of energy, such as electricity, light, or magnetism. This contrasts with analog information, which is conveyed through energy phenomena like sound or light waves.123
Modern information technology relies heavily on digital signals, enabling rapid manipulation and processing of stored information. This digital representation is fundamental to how humans create, access, and use information today. Digital information is stored in complex patterns within binary devices, which are the core components of digital technology. These devices use bits, represented as 0s and 1s, to encode information. Coding systems, like ASCII and EBCDIC, translate characters into these binary combinations, with eight bits forming a byte.123
