Shell is a command-line interpreter that provides text user interface for an Operating System.

Within Emacs you can interact with various shells and other command-line/text-mode programs running as a sub-process within an Emacs terminal emulator:

eshell is a shell (not a terminal emulator, nor a process hosted in one) written in pure Emacs Lisp . It is very powerful, flexible and customizable, but poorly documented at time of writing.

Emacs itself is fully functional either in a terminal or a windowing system. Some keystrokes available under window systems may not work in a terminal and vice versa.

User can use shell inside Emacs, with shell mode, eshell or term.
