'''NetBIOS''' ({{IPAc-en|ˈ|n|ɛ|t|b|aɪ|ɒ|s}}) is an acronym for '''Network Basic Input/Output System'''. It provides services related to the [[session layer]] of the [[OSI model]] allowing applications on separate computers to communicate over a [[local area network]]. As strictly an [[API]], NetBIOS is not a [[networking protocol]]. [[Operating system]]s of the 1980s (DOS and Novell Netware primarily) ran NetBIOS over [[IEEE 802.2]] and [[IPX/SPX]] using the [[NetBIOS Frames]] (NBF) and [[NetBIOS over IPX/SPX]] (NBX) protocols, respectively. In modern networks, NetBIOS normally runs over [[TCP/IP]] via the [[NetBIOS over TCP/IP]] (NBT) protocol. NetBIOS is also used for identifying system names in TCP/IP (Windows).
