NetBIOS

An applications programming interface (API) which activates network operations on IBM PC compatibles running under Microsoft's DOS. It is a set of network commands that the application program issues in order to transmit and receive data to another host on the network. The commands are interpreted by a network control program or network operating system that is NetBIOS compatible. See NetBOLLIX.

NetBIOS

The original networking protocol for DOS and Windows PCs. NetBIOS packets did not contain a network address and were not easily routable between networks. As a result, the interface to NetBIOS and the transport part of NetBIOS were later separated so that NetBIOS applications could use routable protocols such as TCP/IP and SPX/IPX. The programming interface (API) retained the NetBIOS name, while the transport protocol was renamed NetBEUI (pronounced "net-boo-ee").

Name Resolution
Today, NetBIOS is used to support legacy NetBIOS applications but is also widely used for NetBIOS name resolution. Since NetBIOS was the first major standard for PC networks, computers were named according to the NetBIOS format, which identifies a machine by a unique 15-character name. NetBIOS machines periodically broadcast their names over the network so that Network Neighborhood or My Network Places can catalog them.

Datagram and Session Modes
NetBIOS is generally defined as a session layer protocol in the protocol stack, supporting two modes: a fast Datagram mode that does not guarantee delivery and a Session mode that establishes a connection and guarantees delivery. See NetBIOS over TCP/IP, WINS and LMHOSTS file.

Furthermore, NetBIOS provides Name Support to the application programs as well, so that a network node can be addressed--individually by a 16-byte unique name or as a group by a 16-byte group name.
