O
ODI. See Open Data-Link Interface.
Open Data-Link Interface (ODI). Novell’s driver specification for an interface between network hardware and
higher-level protocols. It supports multiple protocols on a single NIC (Network Interface Controller). It is capable of
understanding and translating any network information or request sent by any other ODI-compatible protocol into
something a NetWare client can understand and process.
Open System Authentication. Open System authentication is a null authentication algorithm.

Router. A device that connects networks and supports the required protocols for packet filtering. Routers are typically
used to extend the range of cabling and to organize the topology of a network into subnets. See Subnet.
RS-232. An Electronic Industries Association (EIA) standard that defines the connector, connector pins, and signals
used to transfer data serially from one device to another.
S
Scanner. An electronic device used to scan bar code symbols and produce a digitized pattern that corresponds to the
bars and spaces of the symbol. Its three main components are:
