Terminal Multiplexer

Definitions

1. A program like tmux or GNU Screen that creates multiple virtual terminal sessions within a single terminal window, supporting split panes, named windows, and persistent sessions that survive disconnection — essential for remote work over SSH.

   In plain English: A tool that lets you run multiple command-line sessions in one window and keeps them alive even if you disconnect.

   Example: "I run everything inside tmux so if my SSH connection drops, I just reattach and all my sessions are exactly where I left them."
