Could you clarify for me please, regarding the Dark Vader "Terminal" - is the name now really just a carry over from the old days when computers were accessed through dumb terminals connected by a serial cable, or does it still have some legitimate Terminal options / functions?

Also, CLI - is that just an umbrella term for all of the above, or something different again?

The terminal is the Command Line Interface (CLI), like the DOS interface in Windows.  It's actually an awesome secret weapon, very powerful and in a lot of instances and tasks,  it's actually simpler and easier than using a Graphical User Interface (GUI) (pointy and clicky).  But it used to always made me nervous to use the Terminal, which is why I still think of it as a Sith holocron, lol.
