First of all, let’s start with 32 bit / 64 bit. Our bit is simply one of the most basic units used in computing and digital communications. There are basically two operating systems on your computer: 32 bit and 64 bit. 32 bit / 64 bit is the data passing bus width between our Radom Access Memory (RAM) and the microprocessor, in other words, how the CPU handles datasets. 32 bit and 64 bit This also depends on how much bit system can run on that CPU and how fast.
The working capacity of a 32 bit system is roughly 2 ^ 32 and the range can vary depending on the integer representation. Roughly in the unsigned state, 32 bit can run up to 2 ^ 32 = 4,294,967,295. Similarly, a 64 bit system doubles and can run up to 2 ^ 64 = 1.8 * 10 ^ 19. In other words, 64 bit data transfer rate is almost twice as fast as 32 bit. For one thing, we can only use up to 4 Gb of RAM in a 32 bit system, which is the maximum limited amount of a 32 bit system. However, with special chips, the OS can increase the RAM on 64 bit systems using the Physical Address Extension (PAE) system.
