What are the different beteen vitual teminal and working space in Linux?

Answer 1

A virtual terminat is merely one of the many ways to gain access to a shell in Linux. Usually when a Linux user refers to one, they mean the consoles that can be activated and used through CTRL+ALT+[F1 through F6], as opposed to a TERMINAL EMULATOR, which are usually the "terminal" programs used for accessing a shell from a window manager or desktop environment.

A workspace, on the other hand, is often a term used by certain window managers and desktop environments to refer to virtual desktops. A common feature of *nix GUIs is "multiple desktops" allowing you to organize and spread your applications across more space. They are not like VTs at all. One virtual desktop will still be running in the exact same session as another, and applications running therein will not be in a different session. Further, GUIs in Linux are often VTs, themselves, usually TTY7 through TTY12, whereas CLIs will be on TTY1 through TTY6.
