Questions tagged [8-bit]

In computer architecture, 8-bit integers, memory addresses, or other data units are those that are at most 8 bits (1 octet) wide. Also, 8-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 8-bit is also a term given to a generation of computers in which 8-bit processors are the norm.

An 8-bit number has 2^8 = 256 possible states, 8 bits is one which is why computers with this architecture use bytes as a measurement of storage, for example you can have 64 gigabytes or 64000000000 bytes of memory (RAM).
