What is Linux?

Linux is a set of free use and free dissemination of Unix-like operating system, is a POSIX and UNIX-based multi-user, multi-task, support for multi-threading and multi-CPU operating system. It can run major UNIX tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centered design idea of Unix and is a multi-user network operating system with stable performance.

The Linux operating system was born on October 5, 1991 (this is the first official announcement). There are many different versions of Linux, but they all use the kernel of Linux. Linux can be installed in a variety of computer hardware devices, such as mobile phones, tablets, routers, video game consoles, desktops, mainframes and supercomputers.

Strictly speaking, the word Linux itself only refers to the kernel of Linux, but in fact, people are used to using Linux to describe the entire Linux-based kernel, and use GNU to build operating systems for various tools and databases.

Main characteristics of Linux

Basic thought

The basic idea of Linux has two points: first, everything is a file; second, every software has a definite purpose in which the first item is that everything in the system boils down to a file, including commands, hardware and software devices, operating systems, processes, etc., for the operating system kernel, all are regarded as files with their own characteristics or types. As for the Linux is based on Unix, it is largely because the basic ideas of the two are very similar.

It's completely free.

Linux is a free operating system, users can get it free of charge through the Internet or other means, and can modify its source code at will. This is what other operating systems cannot do. Because of this, countless programmers from all over the world have participated in the revision and writing of Linux, and programmers can change it according to their own interests and inspiration, which makes Linux absorb the essence of countless programmers and grow.

Fully compatible with POSIX1.0 standards

This makes it possible to run the common DOS Windows program through the corresponding simulator under Linux. This lays the foundation for users to switch from the window to the Linux. When many users think about the Linux they use, they think about whether the programs that are common under the previous Windows can work properly, which dispels their doubts.

Multi-user, multi-task

Linux supports multiple users, and each user has their own special rights for their own file devices, which ensures that each user does not affect each other. Multitasking is now the most important feature of computers. Linux enables multiple programs to run simultaneously and independently.

Good interface

Linux has both character interface and graphical interface. In the character interface, the user can input the corresponding instructions through the keyboard to operate. It also provides a similar Windows graphical interface to X-Window 's system, which users can manipulate using the mouse. In the environment of X-Window is similar to that in Windows, it can be said to be a version of Linux's Windows operating system.

Support for multiple platforms

Linux can be run on a variety of hardware platforms, such as those with x86680x0 SPARC, Alpha and other processors. In addition, Linux is an embedded operating system that can run on handheld computers, set-top boxes or game consoles. The Linux 2.4 kernel released in January 2001 has been able to fully support Intel 64-bit chip architecture. Linux also supports multiprocessor technology. Multiple processors work at the same time, which greatly improves the performance of the system.
