What Is Linux? How the Operating System Differs and What It Needs

What is Linux? This question deserves a comprehensive explanation of an operating system whose popularity has grown over 30 years not only among coders and IT professionals but also among individual users. Developed by Linus Torvalds in 1991 as a simple hobby project, Linux has turned into a free and open-source operating system used by millions of people around the world. So let's take a more detailed look at Linux!

What is Linux? How is it different from other operating systems? What is it used for? What are the hardware requirements? The answers to all your questions are in our article!

What Is Linux? 2022

Linux is a free, open-source operating system created by Linus Torvalds. While working on UNIX, the ancestor of operating systems, Torvalds said improvements were needed, but his suggestions were rejected by UNIX's designers. That is how Torvalds came up with the idea of designing an operating system open to the changes and improvements suggested by its users. Linux is actually a kernel; it becomes an operating system together with many other components. The kernel is a program at the heart of the Linux operating system that handles basic tasks such as allowing hardware to communicate with software. Linux commands may seem intimidating at first, but Linux is worth learning because you gain the freedom to make any change you want in the system.

How Is the Linux Operating System Different From Others?

• Linux is an open-source operating system. This means the source code is available to everyone, and you are allowed to contribute to the code, modify it and distribute it without any permission.
• Linux is much more secure than other operating systems, requires no antivirus software and protects the user's privacy. It has a large global community of volunteers constantly looking for ways to improve its security, and with every upgrade the operating system is made more secure and more robust.
• Linux has frequent software updates and high stability. It rarely slows down and rarely freezes, and there is no need to restart after a short time. Because of its stability and reliability, Linux is an operating system widely preferred for server environments. Giants like Amazon, Facebook and Google use Linux for their servers. A Linux-based server can run for years without a restart.
• With different distributions that let you use it according to your requirements, Linux's performance is much higher than other operating systems. Linux allows many people to work efficiently at the same time.
• Network-friendly Linux is also highly flexible. Linux is compatible with a large number of file formats. It can also be installed on any hardware in your old computer system. Even with limited hard disk space, it performs all tasks properly.
• Linux requires few hardware resources. This is one of the most important features that eliminates high resource costs for many companies.

What Is the Linux Operating System Used For?

Contrary to common misconceptions, the fact that Linux is distributed for free and is still being developed does not harm its professional use. The Linux operating system is full of advantages for many specialized uses. For a normal user, Linux works like the Windows or macOS operating system. You can browse the web, check your email, use Office applications, read PDF documents, listen to music, watch videos, view your photos and play games. Today almost all websites run on Linux. In terms of website hosting, setting up a Linux server is really cost-effective. Linux Hosting, which means hosting websites whose programming language is PHP, such as those built with WordPress, on servers with the Linux operating system installed, can also be used for critical web applications.

For advanced users, Linux can be used as an alternative network element and as a router/switch element to connect to multiple networks with different protocols. When used as a router, it can easily be configured as a firewall for security purposes. In addition, it can act as a bridge to separate the traffic of two segments on a network. In most organizations, Linux is used as a terminal server to connect one or more modems.

What Are the Linux Hardware Requirements?
