In computer architecture, 24-bit integers, memory addresses, or other data units are those that are at most 24 bits (3 octets) wide. Also, 24-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

The IBM System/360, announced in 1964, was an extremely popular computer system with 24-bit addressing and 32-bit general registers and arithmetic. Two decades later another popular system, IBM PC/AT, started shipping with its Intel 80286 processor, also with 24-bit addressing, but with 16-bit general registers and arithmetic.
