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.
P

the stop character.
R
RAM. Random Access Memory. Data in RAM can be accessed in random order, and quickly written and read.
RF. Radio Frequency.
ROM. Read-Only Memory. Data stored in ROM cannot be changed or removed.
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.
