32 bit vs 64 bit

computer hardware and software can come in 32 or 64-bit versions the difference between a 32-bit and a 64-bit is the way that it handles memory the bit size refers to the memory that it can address a 32-bit system can reference 2 to the 32nd power bytes of memory which equals to about 4 gigabytes however a 64-bit system can reference 2 to the 64th power bytes of memory which equals to about 16 exabytes which is 4 billion times more memory than a 32-bit now that number is so huge that it's virtually unlimited because we will never need to use that amount of memory so in a computer in order for data or a program to run it needs to be loaded into Ram first so the data is stored on the slower hard drive and from the hard drive it's loaded into the faster Ram and once it's loaded into Ram the CPU can now access the data or run the program now in a 32-bit system since the maximum amount of memory that it can support is 4 gigabytes it may not be enough to hold all the data that th...
