Which number describes a computer's word size?

Answer 1

word size definitionThe number of bits that a CPU can process at one time. Processors with many different word sizes have existed though powers of two (8, 16, 32, 64) have predominated for many years. A processor's word size is often equal to the width of its external data bus though sometimes the bus is made narrower than the CPU to economise on packaging and circuit board costs.

Answer 2

Microprocessors have internal data pathways and internal registers with a fixed number of bits. An 32 bit processor will process 32 bit words, a 64 bit processor will process 64 bit words. The internal registers are sized to accommodate the word length with a single transfer. Generally, the more bits a processor can handle, the faster it can run. Smaller microprocessors might only process only 8 bits or less.
