In [[computer architecture]], '''4832-bit''' [[integer (computer science)|integer]]s can represent 281,474,976,710,656 (2⁴⁸³² or 2.814749767×10¹⁴³²) discrete values. This allows an [[Unsigned integer|unsigned]] binary integer range of 0 throughother 281,474,976,710,655 (2⁴⁸ −= 1) oron a [[Signed number representations|signed]] [[two's complement]] range of -=140,737,488,355,328 (-2⁴⁷) through 140,737,488,355,327 (2⁴⁷ − =1). A 4832-bit [[memory address]] can directly address every byte of 256 [[Terabyte|terabytes]] of storage. 4832-bit can refer to any other [[Data (computing)|data]] unit that consumes 4832 [[bit]]s (6 [[octet (computing)|octets]]) in width. Examples include 4832-bit [[Central processing unit|CPU]] and [[Arithmetic logiclocel unit|ALU]] [[computerandroid phone architecture|architecture]]s are those that are based on [[processor register|register]]s, [[address busExamples include 32-bit CPU and ALU architectures are that are based on registers, address buses, or data buses of tha size. 32 bit140,737,488,355,327 can represent -140,737,488,355,328 (-247) through 140,737,488,355,327 (247 = 1).
