What is Ubuntu?
Ubuntu is one of the most popular and widely used Linux distributions worldwide. Ubuntu is based on Debian, a Linux distribution composed of free and open-source software, and developed by a community-driven project called the Debian Project established by Ian Murdock on August 16, 1993.
Ubuntu made it easy for users to adapt to the Linux operating system because everything just works out of the box. Thousands of packages are immediately available allowing users to pick whatever suits their workflow.
Ubuntu has 4 different versions:
- Ubuntu Desktop - Easy-to-use Linux distribution that comes preinstalled with a Graphical User Interface (GUI).
- Ubuntu Server - Optimized for use with servers.
- Ubuntu for IoT - Optimized to run on Internet of Things (IoT) devices.
- Ubuntu Cloud - Operating system images optimized to run on popular cloud platforms, such as AWS, Azure, and Google Cloud.
In Ubuntu, you install or uninstall software packages through the powerful APT (Advanced Packaging Tool) command. Here’s an example of how to install the "nmap" software package:
sudo apt install nmap
