but as this is the full width of the accumulator and other registers, this could be considered either byte-addressable or word-addressable. 32-bit x86 processors, which address memory in 8-bit units but have 32-bit general-purpose registers and can operate on 32-bit items with a single instruction, are byte-addressable.

The advantage of word addressing is that more memory can be addressed in the same number of bits. The IBM 7094 has 15-bit addresses and could hence address 32,768 words of 36 bits. The machines were often built with a
