Access Point
An access point is a device on a network, such

computers and devices over a LAN in the home
or workplace. Recent computers will be factory
fitted with an Ethernet card and socket.
Filter/Splitter
When you have ADSL broadband your phone

hear the high-pitched noise of data being
sent and received.

goes where it should. Basically it directs traffic.
Routers are great for operating a network that
has more than one device requiring access
to the internet.
SID

being intercepted people they don't know. WEP
is less secure than WPA/WAPI.
