Today, the editor will share with you the relevant knowledge about the difference between Unix and Linux. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

What is Unix?

In the field of IT, Unix, known as the operating system, was developed by AT&T in New Jersey in 1969 (currently its trademark is owned by the International Open Standards Organization). Most operating systems are inspired by Unix, while Unix is inspired by unfinished Multics systems. Another version of Unix is Play 9 from Bell Labs.

Where is Unix used?

As an operating system, Unix is mostly used in servers and workstations, and now it is also used in personal computers. It plays a very important role in creating the Internet, computer network, or client / server model.

The characteristics of the Unix system support multitasking, which is easier than Multics operations. All data is stored in plain text and tree storage with a single root file can access the composition of the Unix operating system with multiple user accounts at the same time.

A) single-core operating system, which is responsible for low-level operations and user-initiated operations, and communication between kernels is carried out through system calls. B) system tools c) other applications

What is Linux?

This is an open source operating system based on the principle of Unix operating system. As open source means, it is a system that can be downloaded freely. It can also customize the system by editing, adding, and expanding its source code. This is one of its biggest benefits, unlike today's other operating systems (Windows, Mac OS X, etc.). The Unix system is not the only template for creating new systems, and another important factor is the MINIX system, unlike Linus, which is used by its creator (Andrew Tanenbaum) for commercial systems.

Linux was developed by Linus Torvalds in 1991 as an operating system of personal interest. One of the main reasons why Linux borrows from Unix is its simplicity. The first official version of Linux was released on September 17, 1991. Although the system was not perfect and perfect, Linus was very interested in it, and within a few days, Linus sent out some emails about Linux source code extensions and other ideas.

Characteristics of Linux

The cornerstone of Linux is the Unix kernel, which is based on the basic features of Unix as well as POSIX and separate UNIX standards. It seems that the official name of the operating system comes from Linus, where the "x" at the end of the operating system name is associated with the Unix system.

Main functions running multitasking (multitasking) programs can contain one or more processes (multi-purpose systems), and each process may have one or more threads. Multiple users, so it can run multiple user programs. Personal accounts are protected by appropriate authorization. So the account accurately defines the control of the system.

The Logo author of Penguin Tux is Larry Ewing, who chose the penguin as the mascot of his open source Linux operating system. Linux Torvalds originally proposed that the name of the new operating system is "Freax", which is the combination of "free" + "freak" + x (UNIX system), unlike the name on the FTP server where its first version is stored (Linux).
