Linux is an open-source, Unix-like operating system (OS) that's known for its reliability, security, and flexibility. Originally created by Linus Torvalds in 1991, Linux has since evolved into one of the most widely used operating systems in the world. Unlike proprietary systems such as Windows or macOS, Linux is open-source, meaning its source code is freely available for anyone to view, modify, and distribute. Linux has become a cornerstone of modern computing due to its open-source nature, security, and versatility. From powering smartphones to servers and supercomputers, Linux plays a pivotal role in the tech ecosystem. Its community-driven development ensures continuous innovation and improvement, which makes it an excellent choice for anyone looking for an alternative to traditional operating systems.
