| Page 137
MAC:
Media Access Control; The unique address a
manufacturer assigns to each networking device.
MTU:
Maximum Transmission Unit; The largest TCP/IP
packet that the hardware can carry.
NAT:
Network Address Translation; NAT technology
translates IP addresses of a local area network to a
different IP address for the Internet.
Network:
A series of computers or devices connected
for the purpose of data sharing, storage and/or
transmission between users.
Network Speed:
Bit-rate on the RF link between units
in a network.
Node:
A network junction or connection point;
typically a computer or workstation.
OIP:
Optimized IP; Compresses TCP and UDP headers,
and filters unnecessary acknowledgements. OIP makes
the most use of the available bandwidth.
OTA:
Over The Air; Standard for the transmission and
reception of application-related information in a
wireless communications system.
PHY:
A PHY chip (also called a PHYceiver) provides the
interface to the Ethernet transmission medium. Its
purpose is digital access of the modulated link (usually
used together with an MII chip). The PHY defines data
rates and transmission method parameters.
Ping:
A network utility used to determine whether a
particular IP address is online.
PLC:
Programmable Logic Controller; An intelligent
device that can make decisions, gather and report
information, and control other devices.
PVID:
Port VLAN ID.
QoS:
Quality of Service; refers to resource reservation
control mechanisms.
RADIUS:
Remote Authentication Dial In User Service; A
networking protocol that provides centralized
authentication authorization, and account
management for computers to connect and use a
network service.
RIPv2:
Dynamic IP routing protocol based on the
distance vector algorithm.
Router:
A networking device connecting multiple
networks.
RS-232:
Industry-standard interface for data transmfer.
RTU:
Remote Terminal Unit; A SCADA device used to
gather information or control other devices.
SCADA:
Supervisory Control and Data Acquisition; A
general term referring to systems gathering data or
performing control operations.
SINAD:
Signal-to-Noise And Distortion; a ratio used as
a measure of the quality of a signal from a
communications device.
SNMP:
Simple Network Management Protocol; A
protocol used by network management systems to
manage and monitor network-attached devices.
SNTP:
Simple Network Time Protocol; A protocol for
synchronizing clocks of computer systems over packet-
switched, variable-latency data networks. Uses UDP as
its transport layer.
Static IP
Address: A fixed address assigned to a
computer or device connected to a computer or device
connected to a network.
Static Routing:
Forwarding data in a network via a
fixed path.
Subnet Mask:
An Ethernet address code determining
network size and determining which addresses belong
or do not on a specified subnet.
Switch:
A device connecting computing devices to host
computers, allowing a large number of devices to
share a limited number of ports.
TCP:
Transmission Control Protocol; A network
protocol for transmitting data that requires
acknowledgement from the recipient of data sent.
TCP/IP:
Transmission Control Protocol / Internet
Protocol; A set of protocols for network
communication.
