I think most all of us here on Lemmy are people with technical background. Most of my professional contacts remained using Reddit, Twitter and even excited when Threads launched.
If you are non-tech background, please comment and share what you do for life.

A server is nothing more than a computer that is always running 24/7.
The server (or actually, computer) can do a lot of different things, such as simply storing a lot of files, streaming these files, download other files, etc.
Besides that, the server can run programs like Lemmy and because the server is generally 24/7, the Lemmy program will also be accessible 24/7.
Edit with an analogy: A server is similar to a literal restaurant-server. People can request data (such as a file) from a server and the server will serve that file to the people who requested it. Just like how people order food from the server in a restaurant, people ‘order’ data (such as a file or image) from the server.
