Today, I will talk to you about the concept of how 32-bit and 64-bit operating systems distinguish from 32-bit and 64-bit. Many people may not know much about it. In order to make you understand better, the editor summarized the following. I hope you can get something from this article.

Sometimes when we download software, the computer system will prompt us to choose whether to install 32-bit or 64-bit ones. Computer professionals who are not professionals will start to get confused. What is 32? What is a 64-bit operating system? What is the difference between them? Let's study it specifically today.

How to distinguish between 32-bit and 64-bit operating systems? To put it simply, x86 represents a 32-bit operating system and x64 represents a 64-bit operating system. If your computer's CPU is more than dual-core, it certainly supports 64-bit operating systems. If your computer has more than 4 gigabytes of memory, you should use a 64-bit system, because both 32-bit Windows 7 and Vista can only support 3.25 gigabytes of memory at most. The 64-bit windows 7 will support up to 128 gigabytes of memory.

The specific differences are as follows:

First, the original intention of the design is different.

The 64-bit operating system is designed to meet customer needs in areas such as mechanical design and analysis, 3D animation, video editing and authoring, as well as scientific computing and high-performance computing applications that require significant memory and floating-point performance. To put it succinctly, they are the operating platforms for high-tech personnel to use the industry's special software. 2144 Mini Game and the 32-bit operating system is designed for ordinary users.

Second, different configurations are required.

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. Of course, the hardware of a 32-bit operating system installed on a 64-bit computer is like a "horse-drawn trolley": 64-bit performance will be greatly reduced.

Third, the operation speed is different

The data width of 64-bit CPU GPRs (General-Purpose Registers, general register) is 64-bit, and the 64-bit instruction set can run 64-bit data instructions, which means that the processor can extract 64-bit data at a time (as long as two instructions, extract 8 bytes of data at a time), which is twice as high as 32-bit (requires four instructions to extract 4 bytes of data at a time). In theory, the performance will be doubled accordingly. Computers

Fourth, different addressing capabilities

The advantage of 64-bit processor is also reflected in the system's control of memory. Because addresses use special integers, an ALU (arithmetic logic arithmetic unit) and register can handle larger integers, that is, larger addresses. For example, Windows Vista x64 Edition supports up to 128 GB of memory and up to 16 TB of virtual memory, h Mini Game, while 32-bit CPU and operating systems support up to 4G memory.

Fifth: software popularity is different.

At present, 64-bit common software is much less common than 32-bit common software. The reason is simple: relatively few users use 64-bit operating systems. Therefore, software developers must consider the "input-output ratio" and put limited funds into the software of more users. This is an important reason why 64-bit software is relatively expensive.

After reading the above, do you have any further understanding of how 32-bit and 64-bit operating systems distinguish from the concept of 32-bit and 64-bit? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
