I’m very torn, because people here are correctly going “nothing”, but then launching on long descriptions of what’s convenient for a server to have. I can’t tell if that is answering your question or if the correct answer is just “a server is any computer that hosts a service for some other computer to access over a network”. Both?
Hell, technically a server doesn’t even need to be a PC at all. You can absolutely have a server and a client be just pieces of software hosted in the same physical machine. “Server” and “client” are just words for what thing is asking for the data and what thing is sending the data over.
