In the computer age, quite a few people mistakenly believed that Unix and Linux operating systems were the same. However, the opposite is true. Let's take a closer look.
What is Unix?
In the field of IT, Unix, known as the operating system, was developed by AT&T in New Jersey, USA in 1969 (its trademark is currently owned by the International Open Standards Organization). Most operating systems were inspired by Unix, and Unix was also inspired by the unfinished Multics system. Another version of Unix is Play 9 from Bell Labs.
Where is Unix used?
As an operating system, Unix is mostly used on servers, workstations, and now on personal computers. It plays a very important role in creating the internet, computer network or client/server model.
Features of Unix Systems
- Support multitasking
- Easier to operate than Multics
- All data is stored in plain text
- Tree storage with a single root file
- Ability to access multiple user accounts simultaneously
Components of the Unix Operating System
a) Single-core operating system, responsible for low-level operations and operations initiated by the user, and the communication between the cores 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 principles of the Unix operating system. As open source means, it is a freely downloadable system. It can also customize the system by editing, adding, and extending its source code. This is one of its greatest benefits, unlike other operating systems today (Windows, Mac OS X, etc.) that have to be paid for. Unix systems are not the only template for creating new systems, another important factor is the MINIX system, unlike Linus, this version was used by its creator (Andrew Tanenbaum) for commercial systems.
Linux was developed in 1991 by Linus Torvalds as an operating system of his own interest. One of the main reasons why Linux borrows from Unix is because of its simplicity. The first official version of Linux (0.01) was released on September 17, 1991. Although the system was not perfect and complete, Linus took a lot of interest in it and within a few days Linus sent out some emails about Linux source extensions and other ideas.
Features of Linux
The cornerstone of Linux is the Unix kernel, which is based on the basic features of Unix and the POSIX and separate UNIX specification standards. It appears that the operating system's official name is taken from Linus , where the "x" at the end of its operating system name is associated with Unix systems .
The main function
- Run multiple tasks at the same time (multitasking)
- A program can contain one or more processes (a multipurpose system), and each process may have one or more threads.
- Multi-user, so it can run multiple user programs.
- Personal accounts are protected by appropriate authorization.
- Accounts thus precisely define system control.
The Penguin Tux Logo was written by Larry Ewing, who chose the penguin as the mascot for his open source Linux operating system. Linux Torvalds originally proposed the name of the new operating system as "Freax", which is a combination of "free" + "freak" + x (UNIX system), not like the first version that stored it FTP server name (Linux).
