Difference between 64-bit computing and Processor register

64-bit computing vs. Processor register

In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory address widths of 64 bits (eight octets). In computer architecture, a processor register is a quickly accessible location available to a computer's central processing unit (CPU).
