Architecture War: 32bit vs 64bit

 

This ‘vs’ was started by the tech crowd when AMD launched their first desktop CPU with a 64-bit architecture, early in 2003. Again when a smartphone with a 64-bit CPU came, it become a hot topic once more. But what does it actually mean for an average customer? Starting with what a bit, very briefly, one bit is a single character in binary either 1 or 0, so it can only express up to 2 values. Now with 2 bits, we can express up to 4 values similarly with 3 bits that go up to 8.
