You’re going to hate me but I’m bad at IT (that’s why I use blocks to create my website!). What do you mean by “server”? I have my computer and only dropbox and google drive to share documents.
The server is the place used to to host the website, so it can be seen by the world and comes through your web host. This can usually be the same place where you registered the domain or another supplier as you prefer, but you would then need to change the name servers.
