LAN messengers are specialized instant messaging applications that are meant to be used within a predefined LAN (Local Area Network).
The main advantage of this type of IM is that it does not even require an Internet connection or a server, since it functions within a private network.
It provides access only to the workstations located inside the network therefore conversations cannot be intercepted by any outsider.
Besides chatting, LAN messengers also support file transfers, emoticons and conferences.
