GNU/Linux is a free open source operating system that began in 1984 as the GNU Project to create a free operating system and in 1991 Linus Torvalds created the Linux kernel; it provides users freedom to use, examine, redistribute, and modify software while preventing others from denying these freedoms and has advantages over Windows like reliability, scalability, flexibility, security, and price. Common desktop applications for GNU/Linux include word processing, programming, graphics, web browsing, email, audio, and games.
