The Computer Word The word size is the computer’s preferred size for moving units of information around; technically it’s the width of your processor’s registers, which are the holding areas your processor uses to do arithmetic and logical calculations. When people write about computers having bit sizes (calling them, say, “32-bit” or “64-bit” computers), this is what they mean. Given the same clock rate, the larger the word then the faster the computer calculates and compares. However, the speed increase depends on the size of the data being calculated. Adding a 16-bit number will not be faster in a computer with 32-bit registers than one with 16 bits, but a 24-bit number will be faster. The 16-bit computer requires additional steps to deal with the 24 bits (16 bits first, then the remaining 8), whereas all 24 bits of the number can fit in the 32-bit register Also, the larger the word size, then the larger the value that the computer can store in memory.
