BASH (Bourne Again SHell) is a shell... not a terminal. You often access BASH USING terminal software (or even a hardware terminal) but it is not the same thing.
Case in point, my terminal software of choice is Putty. I use it to access DASH on Debian on most of my webservers, though a few older hosts are stuck with BASH due to a couple corner-cases where certain shell scripts got broken.
I can also access the Powershell on Windows hosts remotely using Putty since that's ALSO a shell, NOT a terminal.
You might open up a terminal to ACCESS a shell, but they are not even close to being the same thing.
... as my beautiful WYSE WY-50 hardware terminal being used to access the Korn shell on my Sun Blade 2000 proves every time I get a bit of nostalgia.
