Both tmux and screen allow you to attach/detach. Thus you can log off, and you can pick up your session later.
For example, yesterday I logged into a Linux server at DigitalOcean via SSH. I ran tmux, started a long-running job, detached the session. I closed my laptop to go home for lunch. When I returned at my desk, I logged into the server and reattached the tmux session so I could see the results.
