architecture - Why are OS's referred to 64-bit instead of 8-byte? -


why operating systems referred 64-bit , 32-bit instead of 8-byte , 4-byte? wouldn't easier once os's high?

this more era in architectures created - the 1980's. @ time fastest thing slower smart phone right now, why call 4 byte, when unrealistic expect 16 byte computer in life time.

it have been called 4 byte chipset if next version 8 byte, year or 2 later, followed 16 byte shortly after - was, engineers did not foresee incredibly fast growth of microchip, , computer - why name after non-base unit (bits, not bytes)

it similar reason why (have) run out of ipv4 addresses, because group created them (interestingly enough, ipv4 addresses 32 bits long) did not believe there need more in foreseeable future.
