"Screen" is a powerful tool that allows you to create and manage independent terminal sessions on CentOS. Here are some situations where "screen" can be useful:

• Keep sessions active: If you're performing a task on the server and need to close the connection, "screen" allows you to keep the session active even after closing the terminal. This is especially useful when working in a remote environment and need to keep your tasks running.
• Run commands in the background: You can use "screen" to run commands in the background while continuing to work on other tasks. This is ideal for running long scripts, compilation processes, or tasks that require time without affecting your current session.
• Manage multiple sessions: "Screen" allows you to create and switch between multiple terminal sessions easily. You can work on different projects or tasks simultaneously without the need to open multiple terminals or connections.
• Recover lost sessions: In case of a lost connection or unexpected closure, "screen" allows you to reconnect to previous sessions and resume your work without losing data or progress.
