What are 32-bit and 64-bit
The number of bits in a processor refers to the size of the data types that it handles and the size of its registry. A 64-bit processor is capable of storing 264 computational values, including memory addresses, which means it's able to access over four billion times as much physical memory than a 32-bit processor!
32-bit vs 64-bit: What's the Difference?
In the computer world, 32-bit and 64-bit refer to the type of central processing unit, operating system, driver, software program, etc. that utilizes that particular architecture.
32-bit hardware and software is often referred to as x86 or x86-32
64-bit hardware and software is often referred to as x64 or x86-64
32-bit systems utilize data in 32-bit pieces while 64-bit systems utilize data in 64-bit pieces. In general, the more data that can be processed at once, the faster the system can operate.
There are several other advantages to a 64-bit system as well, most practically the ability to use significantly greater amounts of physical memory.
