What is 64-bit?
In laymen terms, 64-bit means that a computer is equipped to process more applications at faster speeds. A 64-bit CPU processes information at faster speeds than the previous 32-bit.
Each bit can have two values so 64 bits can have 264 values and therefore makes this equivalent to over 18,000,000,000,000,000000 values, whereas 32 bits is equivalent to only over 4,000,000,000. (decimal base 10)
This is a bit technical !!! All we really need to know is that 64 bit is faster!
64-bit CPUs can be significantly faster than 32-bit CPUs when performing large number math. That’s because a 32-bit CPU can only hold numbers up to 4,294,967,296, but 64-bit CPUs can hold numbers 4,294,967,296 times larger than that, reducing the number of extra operations your CPU needs to do to handle large numbers. That makes 64-bit CPUs invaluable in many business applications which do a lot of math, but they may not speed up your computer much if all you do is surf the web and read email.
