It is a card that fits inside your Apple computer and connects the computer to wireless networks. Recent Macs will have one already fitted but you will need to add one to older Macs - after checking that they are compatible.
Apple's Airport and Airport extreme are standard Wi-Fi network interfaces. You will need a Wi-Fi network card on a PC to connect to them. A standard Ethernet network card connects with Ethernet cabling and does not work with Wi-Fi.

The 500MHz iBook G3 has the option of adding an Airport card (802.11b) to add wi-fi to the computer but it was not included as standard.

The airport extreme simply makes a relatively small wireless network. The best example of what an Airport Extreme base station is is to compare it to your home phone line and phone. Most people have wireless home phones now. They have a phone line coming into the house and a base station that sends the data received through the phone line to phone handsets somewhere in the house. This is like an Airport Extreme. Your internet provider runs internet to your home (this is the monthly payment). Your Airport Extreme makes a small network which broadcasts the internet in your home. Inside your computer is a wireless card that receives the signal just like your handset on your phone receives the signal from the phone base station. So you don't pay a monthly fee for the Airport Extreme, you pay for the internet that the AE broadcasts. The airport simply makes the internet wireless and your Airport card in your Macbook receives the signal. So you can take the Airport Extreme with you, but you would have to plug it into someone's existing internet that they pay monthly for to get any internet data. The Airport by itself does not have any internet.
Some versions of the iBook have the Airport WiFi card built in while others need an AirPort card to be added, but it needs to be the right one for the particular iBook.
The sim card can be found on the side, with a small hole next to it. You need the ejection tool or similar like a hair grip, staple to open the ejection tray to access the sim card.
