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.
However, limitations and errors can increase, so let’s just say that 32 bit is supported by up to a maximum of 4Gb of RAM. Here we say 32 bit RAM 4 Gb, but our OS does not get full 4 Gb RAM. For example, if a video card uses 1Gb of RAM, the RAM for our Windows OS will be less. On the 64bit system (Home edition), on the other hand, you can use up to 16Gb of RAM. In the Ultimate and professional version, you can increase the amount of RAM up to 192Gb. It has the same video card and 32-bit performance as the RAM, so you can use it without having to run out of RAM. Another thing is that 32-bit software can run on 64-bit systems.
