question about 32 bit addresses??
I have a quick question, I am somewhat confused about this...but I keep reading about 32 bit -vs- 64 bit computers.
Does this mean that for example there are computers for which it can have addresses of 32 bits or maybe 64 bits...
Is my understanding correct??
THanks for any clarification!
The number of bits refers to the data bus.
A 64-bit processor has a 64 bit data bus. The data bus, accumulator(s), & registers are 64 bits (8 bytes) wide. Most processors will have address busses that are wider than their data busses. For example most of the old 8-bit processors had 16 address bits. At least one of the "new" 64 bit processors has a 48-bit address bus... I don't remember which one.
