Do i need networking?

Hi I've been working a small project to learn a little about multiplayer. I can connect 2 computers that have a standalone build of my game. The question is: If I want to make a webplayer version of this game do I have to connect the 2 computers(using network view in the objects and sending information between them and all)? Because the whole game is online and not in the player´s computer so how should I manage a multiplayer web player game?
