Re: Help in PC hardware !!
The 32-bit and 64-bit numbers usualy refer to the width of the data bus that connects the processor core to the memory and external peripherals ,and the size of the processors internal registers. Having a wider bus alows the core to access data at a higher rate and run faster.
Having wide internal registers allows the core to calculate larger numbers without the problems of register overflow.
An 8-bit register can only hold a maximum integer value of 255.
A 64-bit register can hold a very large integer, 2 ^ 64.
If you were to count up from 0 to max int 64.
And you counted 100 million counts per second.
It would take you 7,500 years before you finished!
