Netbeui

n. enhanced version of NetBIOS, network transport protocol used in local area networks based on IBM's Lan Server or Microsoft network systems (Computers)

NetBIOS is an acronym for Network Basic Input/Output System. The NetBIOS API allows applications on separate computers to communicate over a local area network. In modern networks, it normally runs over TCP/IP (NBT), giving each computer in the network both a NetBIOS name and an IP address corresponding to a (possibly different) host name. Older operating systems ran NetBIOS over IPX/SPX or IEEE 802.2 (NBF). NetBIOS provides services related to the session layer of the OSI model.
