What is the difference between 32 bit and 64 bit in linux
This article focuses on "what's the difference between 32-bit and 64-bit in linux". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what is the difference between 32-bit and 64-bit in linux"!
Differences: 1, 64-bit is designed and developed for high-performance applications, 32-bit is developed for ordinary users; 2, 32-bit systems can only support about 3.2 GB of memory, while 64-bit systems support 128 GB of physical memory and 16TB virtual memory.
The operating environment of this tutorial: linux7.3 system, Dell G3 computer.
What is the difference between 32 bit and 64 bit in linux
1. The original intention of the design is different.
64-bit is designed and developed for video, painting, and high-performance applications, while 32-bit is developed for ordinary users.
2. Different configuration requirements
64-bit operating systems can only be installed on 64-bit computers (CPU is 64-bit). The 32-bit operating system can be installed on 64-bit computers.
The 32-bit operating system is installed on a 64-bit computer, and its hardware is like a cart pulling a trolley. 64-bit hardware performance will be greatly reduced.
3. Different operation speed
The data width of 64-bit cpu 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, twice as much as 32-bit, and theoretically double the performance.
4. Different addressing capabilities
When the 32-bit system under linux does not open PAE, it can only support 4G memory.
A 32-bit system can only support a maximum of 3.2 gigabytes of memory. 64-bit systems support up to 128 gigabytes of physical memory and up to 16TB virtual memory.
5. the popularity of software is different.
64-bit software is less than 32-bit software.
At this point, I believe you have a deeper understanding of the difference between 32-bit and 64-bit in linux. You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
