{{Computer architecture bit widths}}
<span lang="th" dir="ltr">In</span> [[computer architecture]], '''8-bit''' [[Integer (computer science)|integer]]s or other [[Data (computing)|data]] units are those that are 8 [[bit]]s wide (1 [[octet (computing)|octet]]). Also, 8-bit [[central processing unit]] (CPU) and [[arithmetic logic unit]] (ALU) architectures are those that are based on [[processor register|register]]s or [[Bus (computing)|data bus]]es of that size. [[Memory address]]es (and thus [[address bus]]es) for 8-bit CPUs are generally larger than 8-bit, usually 16-bit. 8-bit [[microcomputer]]s are microcomputers that use 8-bit [[microprocessor]]s.
The term '8-bit' is also applied to the [[character set]]s that could be used on computers with 8-bit bytes, the best known being various forms of [[extended ASCII]], including the [[ISO/IEC 8859]] series of national character sets{{snd}} especially [[ISO/IEC 8859-1|Latin 1]] for English and Western European languages.
