Explain the difference between 32-bit and 64-bit Windows operating system in general?

Zhang San told me that there was something wrong with his computer, and he had never seen the problem this time, so he asked me what to do.

program is not compatible

I told him this is caused by the word length mismatch between the application and the operating system , Zhang San asked me what is the word length of operating system ? I told him that it was the 32-bit and 64-bit systems that I usually talk about. Zhang San suddenly realized: "I don’t understand! What is a 32-bit system? What is a 64-bit system?"

I said: , for example, a 32-bit system That is, 32 employees work on the assembly line, and 32 products can be brought in at a time when the assembly line is turned on. On a computer, it can handle 32-bit binary numbers at a time.

64-bit system means that 64 employees work on the assembly line, and 64 products are released at a time when the assembly line is turned on. On the computer, it can process 64-bit binary data at a time.

Zhang San said that 64-bit is more efficient than 32-bit , I said of course, not only processing power, 32-bit Windows operating system supports up to 4G of memory , and 64 Bit Windows operating system, maximum support 16T memory.

Zhang Sanyan blinked and said: But 64-bit programs may not run on 32-bit systems. Can 32-bit programs run on 64-bit programs? I said this is completely possible, but your 16-bit application should be too old, the 64-bit operating system does not support it, so an error was reported.

Zhang San said: How do you see how many bits my operating system is?

Right-click on My Computer--->Properties

See how many bits the operating system is

Zhang San said again,Then you haven't solved my problem. I said that if you want to use this program, either finds its 64-bit version, or you install a virtual machine , and then install an operating system that supports 16-bit programs on the virtual machine.

As a result, Zhang San said: After talking for a long time, I can't figure it out. You should install it for me tomorrow!
