How to use AirPort Express A1084 for iMac 3 G4 to connect to?

[3pix]

Hi, I have a old computer (iMac 3 Flat Panel) I want to bring back to life. But I don't know if it's wireless or not. I am trying to use my old AirPort Express A1084 to see if that creates anything to connect to. I plugged my AirPort Express into a outlet near the iMac and it just has a orange light. I am generally confused about all this AirPort Express thing. Can I have help?

As to whether your G4 has wireless, it was optional. Check the socket in the base to see if a card is installed. This video shows where the socket is: www.youtube.com/watch?v=rs0Qo7OO15s

As to how the Airport Express works, it needs Internet service to plug into (eg a cable modem or DSL modem). Do you have that?

Yes I have the yellow cable.
Seems like a ethernet cable.
