  1. I red that 32bit/64bit etc refers to the number of bits manipulated in a single operation, which is usually the size of a register. So this is the same as 1 word? For example a 64 bit Intel CPU has 64 bit words?

    Technically I think you'll find that "word size" is applicable to 64-bit and 32-bit in Intel CPU's. Hardware Word size is equivalent to the Register (i.e. the largest or natural word size which is 64-bit in the 64-bit extension of the x86-64 ISA)
