Linux Ubuntu


Ubuntu is a free and open-source Linux-based distribution based on Debian and powered by millions of desktops around the world. It is developed and maintained by Canonical.

Although Windows and macOS are the most popular desktop operating systems amongst users, Ubuntu is the best alternative because it allows you to do loads of customization that Windows and macOS do not provide.

All the essential applications, like an office suite, browsers, email, and media apps, come pre-installed, and thousands more games and applications are available in the Ubuntu Software Centre.

Ubuntu requires a little bit of a learning curve as compared to Windows and macOS, but it’s not difficult to use. It is free for personal and commercial use.
