Linux is an open-source, Unix-based operating system known for its flexibility, security, and community-driven development model.
What makes Linux special compared to other operating systems is its open-source nature, which allows us to modify and distribute the source code, fostering innovation and a collaborative ecosystem.
Linux’s versatility and reliability make it suitable for a wide range of applications, from personal computers to servers and supercomputers.
