History of Linux
Linux was created by Linus Torvalds, a computer science student at the University of Helsinki, Finland, in 1990. The idea started as a personal project to develop a UNIX-like operating system. A year later, Torvalds’ project transformed into a global phenomenon, and thousands of people began writing UNIX clones.
Today, Linux is used by millions of people: some to study operating systems, others in commercial activities and large companies like Hewlett-Packard, as well as in embedded systems and internet services worldwide.
Strengths of Linux
Flexibility: The Linux source code is freely distributed and can be modified to add new functionalities or to adapt to specific hardware devices.
Interoperability: Linux can work with most existing platforms and other operating systems.
Cost: Linux is free and distributed under the GNU GPL license, allowing the code to be shared and modified.
Unique Features of Linux
Linux maintains the basic look and functionality of UNIX.
It is not a product of a commercial company, but the result of collaboration among developers and users worldwide.
The development of Linux is dynamic and spontaneous, guided by the community of developers and enthusiasts.

Linux Distributions
Linux exists in many distributions, created by various companies and organizations. Each distribution takes the GNU/Linux system base and necessary programs, offering:
A specific installation method
Exclusive programs
Technical support
The difference between distributions is similar to the difference between two car brands: the functionality is similar, but the brand and some features vary.
Conclusion:
Linux is a powerful, flexible, and free operating system that has evolved from a student project into a global phenomenon. It is ideal for users who want full control over their system, to learn, experiment, and engage in professional activities.
