What’s the Difference Between Remote Desktop and Remote Login on Ubuntu?

Hi everyone! I just installed Ubuntu 24.04 for the first time after many years of using computers, and I've got a ton of questions. Right now, I'm curious about the difference between Remote Desktop and Remote Login. From what I've gathered, Remote Desktop allows access regardless of whether a user is logged in, effectively taking over the current session. In contrast, Remote Login seems to start a new session and can even end a current user's session. Is my understanding correct or am I missing something here? I need this clarification because I'm running a Jupyter server with LAN access set up; when I do a remote login and log out, it shuts down my terminal session and the Jupyter server stops working. I'm sure there's a better way to manage this, but I'm still figuring things out!
