Fast Ethernet
An Ethernet system that is designed to operate at
100 Mbps.
GB
Gigabyte.
Group
A Group sets up multiple access rights for a cluster of
Users for a specific Share on the Network Storage Server’s
Administration System.
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.
Hostname
This is the name assigned to the Network Storage
Server upon initial installation.
IEEE
(Institute of Electrical and Electronics Engineers)
This
American organization was founded in 1963 and sets standards
for computers and communications.
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. An IP address consists of 32 bits divided into
two or three fields: a network number and a host number or a
network number, a subnet number, and a host number.
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 1000 metres).
Loop
An event that occurs when two network devices are
connected by more than one path, thereby causing packets to
repeatedly cycle around the network and not reach their
destination.
MAC (Media Access Control)
A protocol specified by the IEEE
for determining which devices have access to a network at any
one time.
MAC Address (Media Access Control Address)
Also called the
hardware or physical address. A layer 2 address associated with a
particular network device. Most devices that connect to a LAN
have a MAC address assigned to them as they are used to
identify other devices in a network. MAC addresses are 6 bytes
long.
