Linux is a computer operating system that is free and open source. The most common operating systems for personal computers are Microsoft Windows, Apple macOS, and Linux. Linux is not prone to crashes and errors that can occur in Windows. It is also very secure, so you do not have to worry about viruses and other malware. There are not as many software applications available for Linux as there are for Windows. Linux can be a good choice for students who want to use it for their studies or for personal use. There is a large community of Linux users and developers willing to help others.
