Why is computer memory always in multiples of 8? (8, 16, 32, 64, 128, 256, etc.)
Because those numbers are powers of two. Computers address memory (and do everything else) with binary numbers. It makes sense to have memory in amounts that line up with powers of two because there's no saving in address space if it doesn't.
The Short Answer
Because those numbers are powers of two. Computers address memory (and do everything else) with binary numbers. It makes sense to have memory in amounts that line up with powers of two because there's no saving in address space if it doesn't. That is, 7KB takes just as much address space as 8KB.
