Ok, smart ass!
So, seriously!
Wireless enabled means that instead of conneting to the internet with a LAN cable or a telephone cord, it has a little antenna in the cover and a low powered transmitter/receiver in the computer.
This will listen for any wireless network base station "WiFi" within range. Your computer will no doubt have a little automated "Wizard" process to connect.
How it works is that you switch it on and it searches for wieless networks within range. You will see a list of them (if any) and their strength, and whether they are secured or public.
You select the network you want and click on Connect.
And you are connected to the internet!
LOTS to look out for security wise so maybe have a read of wikipedia entries for wireless networking.
"Wireless" networking / WiFi / Hot Spot refers to a local netwok maybe within 100 feet of the router. So your neighbours have them etc. It will work jsut fine in Europe/Britain etc.
It is not the same as a cellular modem or connecting through the cellphone system.
