FIREWALL
A firewall is an application that places a virtual security fence around your
computer. As long as it's kept up to date and active, a firewall can stop
hackers from accessing your computer, stop trojans from sending data out
of your computer, and provide you with a report on any such activity.
ROUTER
The term 'router' is used to describe the device which connects your local
business network with your Telstra Business Broadband service (including
the internet, Business Mail and any Telstra Business Broadband Extras that
you may have subscribed to). You can think of your router as being just like
an ADSL modem but with some additional features built in (eg IP routing,
multi port Ethernet switch and Wi-Fi access).
SPLITTER
A splitter is a special filter that separates your internet signal from your
phone (ADSL) or pay-TV (cable) signals. A central splitter is an even more
advanced filter, which is required when you have several outlets on the
same line as your Telstra Business Broadband service.
SSID (OR NETWORK NAME)
The SSID (Service Set Identifier) defines the 'name' of the local Wi-Fi
network provided by your router.
USB
USB stands for 'universal serial bus' and is a system that lets you plug a
huge range of devices (hence the term 'universal') into the one plug (hence
the 'serial bus' part of the term) on your computer. USB connectors are
usually flat, although there is a square model available as well.
