Ubuntu comes with basic applications pre-installed, but additional software can significantly enhance usability. Participants will use the Ubuntu Software Center to install LibreOffice for office productivity (word processing, spreadsheets, and presentations). They will also install web browsers such as Firefox or Chromium to facilitate internet browsing. Other useful applications include GIMP (for image editing), VLC Media Player (for video playback), and educational tools like Khan Academy app or Tux Math for younger users. Participants will also learn how to install applications using the terminal via APT commands (e.g., sudo apt install libreoffice) for a faster and more efficient installation process.
