LAN messenger

A LAN messenger is a type of program that lets people chat to each other over a local area network (LAN). A LAN is a group of computers or other devices joined together, often within the same building, so they can communicate and share information with each other. The LAN messenger works like a normal chat program, but it is only accessible by computers that are part of the same LAN. This means that you can chat with anyone else on the same network as you, but not with anyone outside of it. This is especially useful for workplaces, where there may be a need for secure, private conversations between certain people without worrying about anyone else being able to listen in.
