This article mainly analyzes the relevant knowledge of what are the advantages and disadvantages of the Linux system, the content is detailed and easy to understand, the operation details are reasonable, and has a certain reference value. If you are interested, you might as well follow the editor to have a look, and follow the editor to learn more about the advantages and disadvantages of Linux system.

The operating system is the indispensable system software of the computer and the soul of the whole computer system. Each operating system is a complex computer assembly, which provides the protocol or code of conduct of the operation process. Without the operating system, the computer cannot work, and it cannot interpret and execute commands entered by users or run simple programs.

Generally speaking, the Linux operating system has the following advantages:

Good portability and flexibility: Linux system has good portability, it supports almost all CPU to facilitate cutting and customization, Linux system files can be stored in U disk, CD, can also be widely used in embedded field.

Rich application software: Linux system not only provides users with powerful operating system functions, but also provides rich application software. Users can download not only Linux and its source code from Internet, but also many Linux applications from Internet.

Multi-user, multi-task: like UNIX system, Linux system is also a multi-user, multi-task operating system. Multiple users can use system resources individually, that is, each user has specific rights to their own resources, so that they do not interfere with each other and do not affect each other. At the same time, multiple users can use the computer system at the same time. Multitasking is one of the most important features of modern computers, that is, multiple programs are executed at the same time, but each program runs independently of each other. At the same time, Linux system can schedule each process to access the processor equally.

Reliable security: the Linux system is rarely attacked by viruses and is an operating system with reliable security and immunity to viruses.

In addition to these advantages, for an open system, while it is convenient for users to use, system security is the most important part. Using the firewall, intrusion detection and security authentication tools of Linux, the loopholes of the system can be repaired in time, and the security of Linux system is greatly improved.

Of course, but no matter how perfect the system is, there is room for improvement, and the Linux system also has disadvantages, such as:

Process scheduler: the Linux system kernel provides a scheduler to manage processes running on the system. However, the schedule is pre-emptive, which means that the scheduler allows the process to execute for a period of time, and if the process has not yet completed, the scheduler will temporarily stop the process and start executing another process, which will affect the fluency and consistency of the process.

There is no vendor support: because the software on the Linux system is distributed free and people can download it themselves, there is no support such as after-sales service.

The graphical interface is not friendly enough.

The difference between Linux and Windows

For most beginners, the contact in real life is not Linux, but Windows. As two distinct operating systems, there are the following differences between them.

First of all, the Linux operating system is a modular system. At the bottom of the system, the kernel interacts with the hardware. At the same time, the kernel also represents the application program to control and schedule the resources to be accessed, while the application runs in the so-called user space and requests kernel services by calling a stable system library. The modular design shows that the kernel of the Linux system is independent of any application and interface. The advantage of this is that when an error occurs in the application or there are security vulnerabilities in the program, the error will only be fixed in the application and will not spread to the whole system.

The Windows operating system, on the other hand, is closely related to applications and interfaces. For example, the Windows kernel is highly integrated with the graphical user interface, which seems to improve the efficiency of the system, but in fact, there are great security risks, resulting in system instability.

In addition, in terms of the use of software, the software in the Linux system is basically open-source, which is provided by technical executors all over the country; while the Windows operating system, although it also has free software to use, most of them still need to be authorized by the author.

In the use of the system, the Windows operating system can directly see the graphical interface of the software, which can be operated through the graphical interface of mouse click, while the Linux system is often executed through the command line.

What is Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux can run major Unix tools, applications and network protocols.
