Understanding Linux advantages select Linux

If you are a friend of the Linux operating system, why do you like the Linux system? Linux attracts you from the advantages of Linux. What are the advantages of Linux? This article describes the advantages of Linux.

1. Openness

Openness means that the system complies with world standards, especially the Open Systems Interconnection OSI. All hardware and software developed in compliance with international standards are compatible with each other and can be easily interconnected.

2. Multiple users

Multiple users mean that system resources can be used by different users, that is, each user has specific permissions on their own resources, such as files and devices, without affecting each other. Both Linux and Unix have the characteristics of multiple users.

3. Multi-task

Multi-task is a major feature of modern computers. It means that the computer executes multiple programs at the same time, and each program runs independently of each other. In Linux, every process is scheduled to access the microprocessor equally. Because the CPU processing speed is very fast, the result is that the started application seems to be running in parallel. In fact, there is only a short delay between the processor executing a group of commands in an application and the Linux scheduling microprocessor running this program again, which is invisible to users.

4. Good user interface

Linux provides users with two interfaces: user interface and system call. The traditional Linux user interface is a text-based command line interface (shell), which can be used both online and offline. Shell has strong programming capabilities, allowing users to easily use it to program, thus providing users with more advanced means to expand system functions. A Programmable Shell combines multiple commands to form a Shell program, which can be run independently or simultaneously with other programs.

The system calls the interface used for programming. Users can directly use the System Call commands provided by the system during programming. The system provides low-level and efficient services for user programs through this interface. Linux also provides a graphical user interface. It uses the mouse, menu, window, scroll bar and other facilities to present a user with an intuitive, easy to operate, interactive and friendly graphical interface.

5. device independence

Device independence means that the operating system treats all external devices as files. Any user can manipulate and use these devices as long as their drivers are installed, you don't have to know their specific forms of existence.

An operating system with device independence simplifies the process of adding new devices by treating each peripheral device as an independent file. When a new device needs to be added, the system administrator adds the necessary connections to the kernel. This connection is also called a device driver) to ensure that each time the device is called to provide services, the kernel processes them in the same way. When new and better peripherals are developed and delivered to users, operations allow immediate access to these devices without restrictions after they are connected to the kernel. The key to device independence lies in kernel adaptability. Other operating systems only allow a certain number of external devices or some types of external devices to connect. The device-independent operating system can accommodate any type and any number of devices, because each device is accessed independently through its dedicated connection to the kernel.

Linux is an operating system with device independence. Its kernel is highly adaptive. As more programmers join Linux programming, more hardware devices are added to various Linux kernels and release versions. In addition, because you can get the Linux kernel source code for free, you can modify the kernel source code to adapt to the new external devices.

6. Rich network functions

A complete built-in network is a major feature of Linux. Linux is superior to other operating systems in terms of communication and network functions. Other operating systems do not have the ability to connect networks so closely integrated with the kernel, nor have the flexibility to build in these networking features. Linux provides users with comprehensive and powerful network functions.

Internet is one of its network functions. Linux provides a lot of software that supports the Internet for free. The Internet is established and prosperous in the Unix field. In this regard, Linux is quite convenient to use, users can use Linux to communicate with others in the world over the Internet.
File Transfer is the second of its network function. You can use some Linux commands to transmit internal information or files.

Remote access is the third of its network functions. Linux not only allows file and program transmission, but also provides system administrators and technicians with windows to access other systems. With this remote access feature, a technician can effectively serve multiple systems, even if those systems are located far apart.

7. Reliable System Security

Linux has adopted many security technical measures, including Read and Write Permission control, protected subsystems, audit tracking, and core authorization, this provides the necessary security protection for users in multiple network environments.

8. Good portability

Portability refers to the ability to move an operating system from one platform to another so that it can still run in its own way.

Linux is a portable operating system that can run in any environment from a microcomputer to a large computer and on any platform. Portability provides a means for different computer platforms running Linux to communicate accurately and effectively with any other machine without additional special and expensive communication interfaces.

Free or a little charge: since Linux is a product based on GPL, anyone can freely access Linux. For some publishers of "installation kits, they only need to pay a little fee to release the installation disc! Unlike Unix, which requires huge copyright fees, Microsoft needs to update your system one by one and three again, and pay a lot of fees!
