Linux is everywhere- ranging from smartphones, driving assistance systems, desktops, supercomputers or enterprise servers, and home appliances. 

Among operating systems (OS) such as Windows or Mac OS, Linux is one of the most popular operating systems. Linux itself powers the most commonly used Android OS for mobiles. 

While the use of an operating system is extremely crucial for the communication between the software and hardware in a system, an OS’s efficiency defines the overall performance.

Although Linux is similar to other operating systems available today, its popularity has risen as it is open source. The codes for creating Linux are free and readily available publicly to make any modifications with appropriate functionalities that could be added to improve the performance further.

Linux is versatile with its customization features to add applications, additional software, configure performance or security settings, graphics, and user-interface as per user’s requirements.

Being a feature-packed OS with ample customizable options makes Linux one of the most preferred OS. As technology continues to evolve, high-end workstations are needed to use such technologies for providing the services.

Therefore, the enhanced capabilities of Linux provide robust solutions for high-end mechanisms and technologies while being adaptable and providing an immense amount of libraries and utilities. Thus, professionals in the networking and server support space must be well aware of Linux as it has a constant demand for such experts.
