flow control A congestion control mechanism. Congestion is caused by devices
sending traffic to already overloaded port on a Switch. Flow control
prevents packet loss and inhibits devices from generating more traffic
until the period of congestion ends.
full duplex A system that allows packets to be transmitted and received at the
same time and, in effect, doubles the potential throughput of a link.
half duplex A system that allows packets to transmitted and received, but not at
the same time. Contrast with
full duplex .
hub A device that regenerates LAN traffic so that the transmission distance
of that signal can be extended. Hubs are similar to repeaters, in that
they connect LANs of the same type; however they connect more LANs
than a repeater and are generally more sophisticated.
IEEE Institute of Electrical and Electronics Engineers. This American
organization was founded in 1963 and sets standards for computers
and communications.
IEEE 802.1D A standard that defines the behavior of bridges in an Ethernet network.
IETF Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.
IP Internet Protocol. IP is a layer 3 network protocol that is the standard
for sending data through a network. IP is part of the TCP/IP set of
protocols that describe the routing of packets to addressed devices.
IPX
Internetwork Packet Exchange. IPX is a layer 3 and 4 network protocol
designed for networks that use Novell Netware.
IP address Internet Protocol address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated
with periods (full-stops), and is made up of a network section, an
optional subnet section and a host section.
LAN
Local Area Network. A network of endstations (such as PCs, printers,
servers) and network devices (hubs and switches) that cover a relatively
small geographic area (usually not larger than a floor or building). LANs
are characterized by high transmission speeds over short distances (up
to 1000m).
