Radio frequency. An AC signal of high enough frequency to be used for wireless
communications.
Request For Comments. The name of the result and the process for creating a
standard on the Internet. New standards are proposed and published on the Internet,
as a Request For Comments. The proposal is reviewed by the Internet Engineering
Task Force.
Restriction of the use of certain Hazardous Substances in electrical and electronic
equipment, reference EC Directive 2002/95/EC of 27 January 2003.
Received Signal Strength Indicator. A signal or circuit that indicates the strength of
the incoming (received) signal in a receiver.
Receive
Simple Network Management Protocol. A network management protocol that
provides a means to monitor and control network devices, and to manage
configurations, statistics collection, performance, and security. SNMP works by
sending messages, called protocol data units (PDUs), to different parts of a network.
SNMP-compliant devices, called agents, store data about themselves in
Management Information Bases (MIBs) and return this data to the SNMP
requesters.
Secure Shell is a protocol for secure remote login and other secure network services
over an insecure network.
Transmission Control Protocol. Connection-oriented transport layer protocol that
provides reliable full-duplex data transmission. TCP is the part of the TCP/IP suite of
protocols that is responsible for forming data connections between nodes that are
reliable, as opposed to IP, which is connectionless and unreliable.
Trivial File Transfer Protocol. Simplified version of FTP that allows files to be
transferred from one computer to another over a network, usually without the use of
client authentication.
Transmit
Abbreviation for "Unit" or standard height measurement which defines the vertical
height for plug-in modules in the 19" construction system. One U equals 44.5 mm.
Uplink Channel Descriptor.
User Datagram Protocol. Connectionless transport layer protocol in the TCP/IP
protocol stack. UDP is a simple protocol that exchanges datagrams without
acknowledgments or guaranteed delivery, requiring that error processing and
retransmission be handled by other protocols. UDP is defined in RFC 768.
Up Link
Virtual Local Area Network. A group of devices on one or more LANs that are
configured with the same VLAN ID so that they can communicate as if they were
attached to the same wire, when in fact they are located on a number of different
LAN segments. Used also to create separation between different user groups.
