About GNU Screen

GNU Screen is a terminal multiplexer. It lets you open several virtual consoles inside a single terminal window and switch between separate login sessions without opening new windows or connections.

Its most common use is on remote servers. You can detach a session and reattach it later, so programs keep running after an SSH connection drops or after you log out. It is a long-established tool that suits administrators and anyone who runs long jobs from the command line.
