From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's not installed "in the terminal." It's installed on the computer; the terminal is just one way you might interact with it.
In particular, docker is a type of program called a 'daemon' or 'server': it runs in the background and doesn't have an interface, per se. You can run docker commands and get their output, and you can of course interact with the services you're using docker to run, but there is no "docker app" that runs as a foreground interactive process (either GUI app or ncurses terminal app).
