Linux is a Unix-like, open source and community-developed operating system
for computers, servers, mainframes, mobile devices and embedded devices. It is supported on almost every major computer platform including x86, ARM and SPARC, making it one of the most widely supported operating systems.
Why use Linux?
This is the one question that most people ask. Why bother learning a completely different computing environment, when the operating system that ships with most desktops, laptops, and servers works just fine? To answer that question, I would pose another question. Does that operating system you’re currently using really
work “just fine”? Or are you constantly battling viruses, malware, slow downs, crashes, costly repairs, and licensing fees?
If you struggle with the above, and want to free yourself from the constant fear of losing data or having to take your computer in for the “yearly clean up,” Linux might be the perfect platform for you. Linux has evolved into one of the most reliable computer ecosystems on the planet. Combine that reliability with zero cost of entry and you have the perfect solution for a desktop platform.
That’s right, zero cost of entry…as in free. You can install Linux on as many computers as you like without paying a cent for software or server licensing (including costly Microsoft Client Access License – CALs).
How is Linux operating system used?
Every version of the Linux operating system manages hardware resources, launches and handles applications, and provides some form of user interface. The enormous development community and wide range of distributions means that a Linux version is available for almost any task, and Linux has penetrated many areas of computing.
For example, Linux has emerged as a popular operating system for web servers such as Apache, as well as for network operations, scientific computing tasks that require huge compute clusters, running databases, desktop/endpoint computing and running mobile devices with OS versions like Android.
