Have you tried using a real-time USB drive to run the Linux operating system? This is a simple and easy way to understand how Ubuntu works and become familiar with the user interface (UI) and layout. Using real-time USB, you can start the system, install programs, save projects, and configure without changing the computer configuration. However, please note that once the system is restarted, all saved items and changes will be cleared. If you just try the operating system once, this is not a problem. If you want to save your files and settings so that you don't have to start from scratch, you can create a permanent USB drive by installing the operating system on it.

This article will explain how to run Ubuntu 20.04 from a USB stick. The article will also explain how to install Ubuntu on a USB drive to make the drive persistent. The primary topics covered in this article include the following:
