A variety of client systems can use wireless or wired technology to communicate with Domino® servers over local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). For example, Notes® workstations and Domino servers use the Notes remote procedure call (NRPC) protocol running over the LAN's network protocol to communicate with other Domino servers. Other client systems, such as Web browsers, Internet mail clients, wireless application protocol (WAP) devices, and personal information management (PIM) devices, can also communicate with Domino servers.
