The usage and performance of a system depend on its specifications. What kind of processor it has? Which version of the operating system runs? How much disk space is left? You may require these parameters during the installation or configuration of different software.
In this article, we will show you how you can check system and hardware details using command-line and GUI in Ubuntu 20.04 (Focal Fossa).
Method # 1: Using Command-Line
