Question: How is IBook and AirPort connected?

full_context: Document 1: Air Transport Network: Air transport network or air transportation network (ATN) is an example of transport networks and spatial networks. The nodes of the network are the airports and the links represent direct flight routes between two airports. Alternatively, cities can be considered as the nodes with links representing direct flight connection between them. Air transport networks can be defined worldwide as well as for one region or for one airline company; the scale of the network can be global or domestic.
Document 2: Apple I: Apple Computer 1, also known later as the Apple I, or Apple-1, is a desktop computer released by the Apple Computer Company (now Apple Inc.) in 1976. It was designed and hand-built by Steve Wozniak. Wozniak's friend Steve Jobs had the idea of selling the computer. The Apple I was Apple's first product, and to finance its creation, Jobs sold his only motorized means of transportation, a VW Microbus, for a few hundred dollars, and Wozniak sold his HP-65 calculator for $500; however, Wozniak said that Jobs planned to use his bicycle if necessary. It was demonstrated in July 1976 at the Homebrew Computer Club in Palo Alto, California.

Document 5: Apple IIc: The Apple IIc, the fourth model in the Apple II series of personal computers, is Apple Computer’s first endeavor to produce a portable computer. The result was a 7.5 lb notebook-sized version of the Apple II that could be transported from place to place. The "c" in the name stood for "compact", referring to the fact it was essentially a complete Apple II computer setup (minus display and power supply) squeezed into a small notebook-sized housing. While sporting a built-in floppy drive and new rear peripheral expansion ports integrated onto the main logic board, it lacks the internal expansion slots and direct motherboard access of earlier Apple IIs, making it a closed system like the Macintosh. However, that was the intended direction for this model — a more appliance-like machine, ready to use out of the box, requiring no technical know-how or experience to hook up and therefore attractive to first-time users.

Its objective is to transport the resources of the Intelligent Network to the wireless network, utilizing the TIA-41 set of technical standards. Basing WIN standards on this protocol allows changing to an intelligent network without making current network infrastructure obsolete.
Document 13: ISync: iSync is a software application first released by Apple Inc. on Jan 2, 2003. Apple licensed the core technology from fusionOne.
