Today, I will talk to you about how to compare Linux system with Windows system. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

There are many systems commonly used in our lives, such as Linux, Windows and Unix. Among these systems, Linux and Windows are the most common, so what's the difference between these two systems? Let's take a look at it from all aspects.

Linux is an operating system that mainly runs on inetel architecture. It not only has all the characteristics of Unix system, but also is compatible with POSIX standard. The functions of Linux include true multitasking, virtual memory, shared libraries, demand loading, etc., and issue a general public license that complies with GNU. However, the Windows operating system has a completely different development mode and history from Linux.

1. Process management and scheduling: in this respect, Linux is a monolithic operating system, and the operating system is usually carried out in the memory space of the user's process, which can avoid the overhead of process switching when the system call occurs. Windows is a quasi-microkernel operating system, and many functions are implemented by separate processes, which improves the modularization of the system, but the cost of process switching is higher.

2. Inter-process communication mechanism: Linux provides a standard UNIX IPC mechanism, while Windows provides many advanced IPC mechanisms directly oriented to applications on the basis of the basic IPC mechanism. In essence, the IPC mechanism of Linux is close to the IPC primitive, which provides the greatest flexibility, and more replicated IPC value can also be established on this basis, while the IPC mechanisms provided by Windows in the primitive include pipe, named pipe, message passing, shared memory, semaphore and so on.

3. Memory management: Linux is better than Windows. When facing the same process address space, the use of memory layout is different. Windows only prepares the weak virtual address space of 2GB for the process, while the process address space in Linux is more flexible.

Although both Linux and Windows provide memory sharing technology, they achieve some differences in thinking. Linux systems give users a very simple interface and only need to attach their own virtual memory space to shared memory objects. Windows provides a shared memory mechanism through memory-mapped files, which is more complex in terms of use.

After reading the above, do you have any further understanding of how to compare Linux system with Windows system? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
