About Gigabit Ethernet
Gigabit Ethernet is a 1Gbps (1000Mbps) extension of the IEEE 802.3 Ethernet networking standard.
Its primary applications are in corporate LANs, campus networks and service provider networks where
it can be used to tie together existing 100Mbps Ethernet networks.
About the Dimension GS-1116A and GS-1124A Gigabit Switch
The GS-1116A or GS-1124A is designed to improve your network performance with high-speed data
transmission over copper wire. The GS-1116A or GS-1124A provides an ideal upgrade path for
existing Ethernet-based networks that need more bandwidth. It can be installed as a backbone network
while retaining existing investments in Ethernet hubs, switches and wiring infrastructure.
General Syntax Conventions
For brevity’s sake, we will use “e.g.” as shorthand for “for instance”, and “i.e.” as shorthand for “that
is” or “in other words” throughout this manual.
