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.

People have already made lots of good replies but here's my summary:
tmux is a terminal multiplexer. It allows multitasking in command line only environments. For example if you have to do a sudo apt upgrade but don't want to leave your ssh client logged in until it finishes, you can run it in a tmux session so it will happen in the background even if you're not logged in.
To start a new session, type "tmux"
To view running sessions, type "tmux list-sessions"
To switch to a running session, type "tmux attach-session -c N" where N is the number of the session.
To exit a tmux terminal and go back to the main terminal, do ctrl+b and then press d.
