This article mainly introduces the use of learning linux, the article is very detailed, has a certain reference value, interested friends must read it!

The use of learning linux

1. Improve efficiency. (this is really a matter of opinion.)

two。 Higher learning costs mean that you can learn more, but it also means that you may waste a lot of time.

Extended data

Linux is a free-to-use and free-spread Unix-like operating system. It is a multi-user, multi-task, multi-threaded and multi-CPU operating system based on POSIX and UNIX. It runs major UNIX tools, applications, and network protocols. It supports 32 bit and 64 bit hardware. Linux inherits the design idea of Unix with network as the core, 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 time it has been officially released). There are many different Linux versions of Linux, but they all use the Linux kernel. 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 Linux kernel, but in fact people have become accustomed to using Linux to describe the entire Linux kernel and use GNU to project operating systems with various tools and databases.

Main characteristics

Basic thought

The basic idea of Linux has two points: first, everything is a file; second, every software has a definite purpose. The first one is that everything in the system boils down to one file, including commands, hardware and software devices, operating systems, processes, and so on, which are regarded as files with their own characteristics or types for the operating system kernel. As for the fact that 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 modification 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 common DOS and Windows programs under Linux through the corresponding simulator. This lays the foundation for users to move from Windows to Linux. When many users think about using Linux, they think about whether the programs that used to be common under Windows will work properly, which relieves them of their doubts. [4]

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 X-Window system similar to the Windows graphical interface, which can be manipulated by users using the mouse. In the X-Window environment is similar to in Windows, it can be said to be a Linux version of Windows.

Support for multiple platforms

Linux can run on a variety of hardware platforms, such as those with x86, 680x0, SPARC, Alpha and other processors. In addition, Linux is an embedded operating system that can run on PDAs, 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.
