I just sent one email which I got into some of the start places. But I
didn't answer one of your questions. What is WiFi, stands for in general
WireLess or Wire Free connection to Internet. First you have a high
speed Internet connection to your house or business. Then connected to
that can be a PC for high speed. But usually one wants to attach a
router to the cable modem and connect PC or PCs to the router. Reason is
that a router can act as a firewall between the PCs on your network and
the Internet. View the Internet as the wild west with all the outlaws
and indians out there looking to get you. All indians please pardon my
use of this view. The router (firewall) is the fort giving protection to
all those inside. Now you can get routers with built in WiFi which
allows the PC equipped with WiFi transceivers to connect to the router
when in range of the router.
Steve did I say anything about a new learning experience, well it may
become clear that you have started on a learning experience. It will be
fun.
I hope this helps as a start, keep asking questions, there a lot of
people to answer them for you.
