Linux is a Unix-like computer operating system assembled under free and open-source software development and distribution model. It hides the technical details of how software and hardware communicate with you, just like Windows or OS does. It’s a free spirit just like its creator Linus Torvald; the man behind it. Pros and Cons of Linux is an open-licensed system, which means it’s wholly developer-friendly, and you may distribute your modified version to help other people.
