Short answer for : AirPort was Apple’s name for its Wi‑Fi hardware family (cards plus base stations). There were two main user‑installable card lines — the original AirPort (802.11b) and the later AirPort Extreme (802.11g) — and they use different form factors, so they are not interchangeable. AirPort (overview). (en.wikipedia.org)

To see what your machine actually has, open Apple menu → About This Mac → System Report (System Information) and look under Network → Wi‑Fi (older OS X labels it AirPort). That view shows whether the OS sees a wireless card and gives the model/firmware. For specific models (for example, some iMac G5 configurations were sold “AirPort Extreme ready”), check the Mac’s tech specs on Apple’s site before buying parts. How to get system information on a Mac · iMac G5 technical specs. (support.apple.com)

If you need wireless and the Mac accepts the correct Apple card, install the matching AirPort or AirPort Extreme card for that model — do not try to force the wrong family into the slot. If your Mac has no slot (or you don’t want to open it), practical alternatives are a small bridge/router like Apple’s AirPort Express (it can join an existing network in “client” mode for audio/print bridging) or a supported USB/Ethernet Wi‑Fi adapter. When buying used parts, match part numbers/model IDs; the Extreme cards were backward‑compatible at the network level but not physically interchangeable. [Macworld on AirPort Extreme] (https://www.macworld.com/article/157481/apple-9.html) · Ars Technica on AirPort Express modes. (macworld.com)

Quick troubleshooting: if Wi‑Fi is missing from System Report the OS doesn’t see hardware — try reseating the card (on older machines), check connectors, and confirm the OS version supports that card. If you just need internet at the desk, Ethernet is still the simplest option. For model‑specific guidance, post the Mac model identifier (e.g., iMac5,1 or PowerBook3,2) and the community can point to the exact part/slot you need.

Its a card for wireless networking

If you have an earlier iMac (g4 or g5) chances are you do not have a wireless card which Apple refers to them as AirPort cards. If you already have a wired network - you may not need it.

A AirPort card is a wireless card for Mac's and all the new models have them built in so if your buying a new Mac its already inside it. And it allows you to connect to any wireless internet network allowing you to surf the internet from any hotspot provided you know the wep password (if it is a password protected newtork).
