What is the difference between a 32-bit system and a 64-bit system

                                                                                                                                                                                         When installing the system and installing the software, do you often see the two terms 32-bit (x86) and 64-bit (x64). What do you mean by 32-bit and 64-bit? What is the difference between the two? Xiaobian will take you to understand the difference between the 32-bit system and the 64-bit system.
32-bit and 64-bit processors
Because the
CPU
CPU has 32-bit and 64-bit, it has 32-bit and 64-bit systems. To install a 64-bit system, you must use a 64-bit CPU. There is no limit to a 32-bit system. How do you judge your own computer
CPU is 64-bit? If you are a computer bought in the past 4 years, you can definitely be 64-bit. If you are not sure you can use CPU-Z to view, the 64-bit CPU instruction set has x86-64 and 32-bit x86.
The simple difference between 32-bit system and 64-bit system
The specific technical details are not told to you. Xiaobian only talks about two differences that are closely related to the usual use of computers.
1.32 bit system actually only supports <4GB memory, 64-bit system can support up to 128GB memory. If the computer has a 4GB memory stick installed, but a 32-bit system is installed, the actual available memory is <4GB, and the 64-bit system is 100% usable.

2.64 bit system supports 32-bit and 64-bit software, 32-bit system supports 32-bit software. If you encounter certain software that indicates x64, you should be using 32. Bit. The old games and software are all 32-bit. When running these games and software on a 64-bit system, it runs in 32-bit compatibility mode, and there may be problems that cannot be run.
Check if the system is 32-bit or 64-bit.
1. Right click on ”Computer
<quo;(Win8 is "This computer").

2. Select the attribute, you can see if the system is 32-bit or 64-bit in the system type.

If you need to replace the 32-bit system you are using with a 64-bit system.
