Linux is a multi-user system, which allows many users to work on it simultaneously. So what if different users need to work on the same system at a time? How do you do that? This is where we need the virtual terminals, let us learn about them.
What are Virtual Terminals?
Virtual Terminals are similar to Terminal that you have been using so far. They are used for executing commands and offering input. The only difference is that you cannot use the mouse with the Virtual Terminals. Therefore, you need to know the keyboard shortcuts.
Virtual Terminals enable a number of users to work on different programs at the same time on the same computer. This is the reason they are one of the most distinguished features of Linux.
Let us learn how to access and utilize them.
