Utvecklingen av hårdvaruformgivningen sammanlöpte på den vanligaste implementationen av användningen av 8 bitar per byte, eftersom det är vitt använt idag. På grund av tvetydigheten i att förlita sig på den underliggande hårdvaruformgivningen, definierades enheten <a href="/wiki/Oktett_(datavetenskap)" title="Oktett (datavetenskap)">oktett</a> att uttryckligen ange en sekvens av 8 bitar. </p><p>Datorer brukar manipulera bitar i gruppar om en fast storlek, konventionellt kallade ”<a href="/wiki/Ord_(datorterm)" title="Ord (datorterm)">ord</a>”. Liksom byte, varierar även antalet bitar i ett ord med hårdvaruformgivningen, och det är typiskt mellan 8 och 80 bitar, eller ännu mer i vissa specialiserade datorer. Från och med 2000-talet, har persondatorer och serverdatorer i detaljhandeln en ordstorlek på 32 eller 64 bitar. </p><p>SI definierar en serie <a href="/w/index.php?title=Decimalprefix&action=edit&redlink=1" class="new" title="Decimalprefix [inte skriven än]">decimalprefix</a> (<a href="/wiki/SI-prefix" title="SI-prefix">SI-prefix</a>) för multipler av standardiserade enheter, vilka även frekvent används för bit och byte.
