In computer architecture, 48-bit integers can represent 281,474,976,710,656 (2⁴⁸ or 2.814749767×10¹⁴) discrete values. This allows an unsigned binary integer range of 0 through 281,474,976,710,655 (2⁴⁸ − 1) or a signed two's complement range of −140,737,488,355,328 (−2⁴⁷) through 140,737,488,355,327 (2⁴⁷ − 1). A 48-bit memory address can directly address every byte of 256 terabytes of storage. 48-bit can refer to any other data unit that consumes 48 bits (6 octets) in width. Examples include 48-bit CPU and ALU architectures that are based on registers, address buses, or data buses of that size.
