Airport (standard on certain PowerBooks?)

[abarone300]

Hi
I have three Powerbooks, of which two have 1.67Ghz and one has a 1Ghz processor. The two that have the 1.67Ghz processor, also have Airport.
The third PowerBook doesn't have Airport.
My question is: is Airport standard on certain PowerBooks? or is it just coincidence that the faster processors have it.

Is Airport an inboard modem, or is it like the one installed on PC notebooks?

Is the "Airport" equipped PowerBook also predisposed and equipped with an antenna. Thanks

Aldo

Your PowerBook is capable of having an Airport card installed, just the more expensive ones had one already installed.
Here is how you can do that: http://docs.info.apple.com/article.html?artnum=95133

Airport is also Apple's name of Wireless LAN, so an Airport card is not a modem (a different device, that dials up to a service provider via a telephone line), but a network interface like the ethernet ports on many computers.
It just doesn't need wires, but a router, that has created a wireless network, to which your computer can connect via the Airport card.
You can also create your own wireless LAN with your computer, but just to share files or even an internet connection that you get somehow else, like via LAN or a direct connection to a modem.
