The terminal in Linux is basically a software representation of the physical terminals that existed earlier, running in a Graphical User Interface (GUI). This terminal offers you an interface through which Linux users could type commands, and could print the outputs. Linux is one of the most sought-after skills required in new technologies, like cloud computing, etc. If you wish to get trained and skilled in Linux, I would suggest you have a look at the Linux course from Intellipaat, which offers you with 16hrs of instructor-led training and 32hrs of guided projects and exercises to help you acquire practical skills.
