Sa ofisom nikakve veze, u pitanju je mašinska reč.
Iz gugla:
mašinska reč, računarska reč.
- Vektor sačinjen od bitova koji se u računaru od strane
hardvera tretira kao jedna celina.
- Broj bitova u reči govori o dužini reči (ili veličini reči) i
danas najčešće iznosi 32 ili 64 sa tendencijom daljeg
povećanja.
In common usage, the word size refers to the size of a processor register. On a 32 bit processor, this will be 32 bits. On a 64 bit processor, this will be 64 bits.
The bit size of the processor is somewhat independent of the bit size of the OS. For example, you can run 32 bit windows on a 64 bit processor. Your word size will still be 64 bits, but programs won't be able to address the entire processor word.
In legacy Windows programming, there is a macro defined called WORD, who's size is 16 bits. This made sense when processors were 16 bit. However, even when you compile code that contains this macro for a 32 bit or 64 bit target, it will still be 16 bits.
Elem, pitanje nije precizno definisano i kao takvo može imati više tačnih odgovora.
