NVM. Non-Volatile Memory.
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
PAN . Personal area network. Using Bluetooth wireless technology, PANs enable devices to communicate wirelessly.
Generally, a wireless PAN consists of a dynamic group of less than 255 devices that communicate within about a 33-foot
range. Only devices within this limited area typically participate in the network.
Parameter. A variable that can have different values assigned to it.
PING. (Packet Internet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to
test and debug a network by sending out a packet and waiting for a response.
Programming Mode. The state in which a scanner is configured for parameter values. See Scanning Mode.
Q
Quiet Zone. A clear space, containing no dark marks, which precedes the start character of a bar code symbol and follows
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.
