Welcome to the Linux for Beginners learning module. This course takes you from zero knowledge of Linux to confidently administering an Ubuntu server — including installation, user management, SSH access, networking, remote desktop, and performance tuning.
By the end of this course you will be able to:
- Explain what Linux is and choose the right distribution for your needs
- Install Ubuntu Server in a virtual machine or on bare metal
- Navigate the Linux filesystem and understand the directory structure
- Create and manage users and groups
- Connect to a server securely over SSH
- Run essential command-line operations and manage packages
- Create and manage files and directories
- Configure the UFW firewall and basic networking
- Set up a swap file to extend server memory
- Enable a graphical Remote Desktop (xRDP) session
- Monitor system performance with
htop
