Linux Operating System has it's usage in supercomputers, web servers, desktops, laptops, and home appliances such as washing machines, modems, routers, and refrigerators. Linux is also known to be used in Smart Devices, Servers and Mainframes, Gaming, Supercomputers, etc.

Linux is a freely distributable version of Unix. In 1991, Linus Torvalds, a student at the University of Helsinki in Finland, began his project to create a freely available academic version of Unix. This project later became the Linux kernel.

Today, Linux OS is used in supercomputers, web servers, desktops, laptops, and home appliances such as washing machines, modems, routers, and refrigerators.

Both the operating system courses are good in their own way. The students who are into programming languages can prefer to study Linux as it supports multiple programming languages. The students who are interested in learning networking and related concepts can study Windows operating systems. Both the courses provide extensive knowledge of the respective operating systems.

Certifications such as CompTIA Linux+, Microsoft Certified: Azure Administrator Associate, Certified Information Systems Security Professional (CISSP), and Red Hat Certified Engineer (RHCE) can enhance your credibility and job prospects in operating systems-related roles.

To prepare for a career in operating systems, you should be pursuing relevant courses (e.g., computer science, information technology), doing internships & personal projects, and staying updated on industry trends and technologies. 

Current trends include the integration of operating systems with cloud computing and IoT, advancements in security features, and the rise of edge computing. Challenges include cybersecurity threats, ensuring compatibility and interoperability, and managing the complexity of modern operating systems.

CompTIA Linux+, Microsoft Certified: Azure Administrator Associate, Certified Information Systems Security Professional (CISSP), and Red Hat Certified Engineer (RHCE) can enhance your operating System skills and help you land a good-paying job.
