What is the difference between Win7 64-bit system and Win7 32-bit system

There are four differences between windows7 64-bit and 32 flagship edition:

Difference one: the ability to process data

The CPU of a 32-bit computer can handle up to 32-bit data at a time. For example, its EAX register is 32-bit. Of course, 32-bit computers can usually handle 16-bit and 8-bit data. 64 processing data for the computer at a time is much larger than 32-bit data, running 64-bit data at a time.

Difference 2: different supported memory (different addressing capabilities)

Many 32-bit systems support 4G memory, while 64-bit systems can support hundreds of gigabytes of memory.

Difference 3: different architectures

The change from 32-bit to 64-bit architecture is a fundamental change, as most operating systems must make comprehensive changes to gain the benefits of the new architecture. Other software must also be ported to use new performance; older software is generally supported by hardware compatibility mode (the new processor supports the older 32-bit version of the instruction set) or software emulation.

Or implement a 32-bit processor core directly in a 64-bit processor (like Intel's Itanium processor, which contains an x86 processor core to execute 32-bit x86 applications). An operating system that supports 64-bit architecture, generally supporting both 32-bit and 64-bit applications.

Difference 4: different requirements for configuration

64-bit operating systems can only be installed on 64-bit computers (CPU must be 64-bit). At the same time, 64-bit common software needs to be installed for 64-bit (x64) optimal performance. 32-bit operating systems can be installed on 32-bit (32-bit CPU) or 64-bit (64-bit CPU) computers.

Can 64-bit operating systems coexist with 32-bit operating systems? The answer is yes, you can install dual systems to solve the problem, but you need to note that you can only recognize 4GB on 32-bit systems with more than 4G memory, so if you are installed with large memory, you should choose the 64-bit system. After all, the latter is more advanced. I believe you all have a certain understanding of the difference between win732 bit and 64 bit.
