What is the difference between the width of the notebook and whether it is sixty four or thirty two

The system is divided into those two! Sixty-four's compatibility is not good.

Difference between 32-bit system and 64-bit system:

First, the original design intention is different. The 64-bit operating system is designed to meet the needs of customers who require large amounts of memory and floating-point performance in areas such as mechanical design and analysis, 3D animation, and authoring, as well as scientific computing and high-performance computing applications.

In other words: they are the operating platforms for high-tech personnel to use the special software of the industry. Whereas, the 32-bit operating system is designed for the average user.

Second, the requirements are different. A 64-bit operating system can only be installed on a 64-bit computer (the CPU must be 64-bit). At the same time, you need to install common 64-bit software to get the best performance out of 64-bit (x64).

A 32-bit operating system can be installed on a 32-bit (32-bit CPU) or 64-bit (64-bit CPU) computer. Of course, a 32-bit operating system is installed on a 64-bit computer, and its hardware is like a "big cow pulling a small car": 64-bit performance will be greatly reduced.

Third, the speed of operation is different. The data width of 64-bit CPU GPRS (General-Purpose Registers) is 64 bits, 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 (only two instructions, extract 8 bytes of data at a time), which is twice as high as 32-bit (requires four instructions and extracts 4 bytes of data at a time), and theoretically the performance will be increased by 1 time.

Fourth, the addressing capabilities are different. The advantage of a 64-bit processor is also reflected in the system's control over memory. Since the address uses a special integer, an ALU (arithmetic logic combinator) and registers can handle larger integers, i.e. larger addresses.

For example, Windows Vista X64 Edition supports up to 128 GB of RAM and up to 16 TB of virtual memory, while 32-bit CPUs and operating systems can only support up to 4GB of RAM. Imperial Clear.

Fifth, the popularity of software is different. At present, 64-bit common software is much less common than 32-bit common software. The reason is simple:

There are relatively few users with 64-bit operating systems. Therefore, software developers must consider the "input-output ratio" and invest limited funds in software with a larger user base. This is also a big reason why 64-bit software** is relatively expensive (spread the cost into fewer releases).

All in all, the Microsoft Windows 64-bit operating system must be "up" supported by 64-bit host hardware, and "down" by the assistance of 64-bit common software, in order to give full play to the advantages of 64-bit, and the "trinity" is indispensable (the reason is very simple: the operating system is just a running platform that connects the previous and the next). As for 64-bit computers that can install 32-bit operating systems, and 64-bit operating systems can install 32-bit software, that is "backward compatibility" in design, not the original meaning of 64-bit design.

The difference between a computer's 64-bit and 32-bit is mainly in terms of system performance and memory usage, as well as compatibility with software programs.

Compared with 32-bit systems, 64-bit systems can make full use of the computer's memory, can support higher memory capacity, and can also process data and perform tasks faster, which will be better for work that requires a lot of data processing and calculation, such as images, **, simulations and other programs. For general office and entertainment use, the 32-bit system is sufficient.

Second, 64-bit systems have problems with the compatibility of some software programs compared to 32-bit systems. Since some software programs only support 32-bit systems, if you use a 64-bit system, you need to solve the compatibility problem in other ways, such as running these software programs through virtual machines or emulators.

Both 64-bit and 32-bit have their own scenarios. If you need to handle large amounts of data and perform some high-standard calculations, then a 64-bit system is obviously a better choice, while if you are just doing some simple work and entertainment activities, then a 32-bit system will be enough for your needs.

The main differences between the 32-bit and 64-bit computer operating systems are due to the following:

The memory addressing capability is different: a 32-bit operating system can only support up to 4GB of memory, while a 64-bit operating system can support more memory, even up to the terabyte level of memory.

Different system performance: 64-bit operating systems have greater advantages in processing performance and computing power than 32-bit operating systems, and can better support high-performance hardware such as multi-core processors.

Software compatibility is different: a 64-bit operating system cannot run 32-bit applications, while a 32-bit operating system can run both 32-bit and 64-bit applications. Due to historical reasons, many software are only available in 32-bit versions, so you need to consider software compatibility when choosing an operating system.

Different system stability: Compared with 32-bit operating systems, 64-bit operating systems have better performance in system stability and can better ensure data security and stability.

It should be noted that when choosing an operating system, you need to choose according to your own computer hardware configuration and software requirements, if the computer hardware configuration is high-end, you need to run large applications or high-performance computing, it is recommended to choose a 64-bit operating system, if not, you can choose a 32-bit operating system.
