Example text

20 C ha pt er 2 Figure 2-8: The IrDA port on a laptop computer often looks like a blank panel on the edge of the case. As you have probably noticed with your TV’s remote control, infrared signals can bounce off walls and other objects, so it’s not absolutely necessary to point a pair of IrDA ports directly at each other, especially when they’re both indoors. When two computers with active IrDA ports are in the same room, they will usually detect each other automatically. NOTE The infrared port on a laptop computer can detect an IrDA signal from another computer in the same room and automatically set up a network link between the two devices.

That same pattern repeats every time you add another layer of activity to a communications system. Each layer may attach additional information to the original message and strip off that information after it has done whatever the added information instructed it to do. By the time a message travels from a laptop computer on a wireless network through an office network and a gateway to the Internet, and onward to a distant computer connected to another local network, a dozen or more information attachments might be added and removed before the recipient reads the original text.

Reserved Addresses As Chapter 3 explained, your LAN communicates with other networks through a router. As far as the networks connected to that router are concerned, the router is just one more network connection with an IP address. Therefore, as Figure 4-1 shows, a router has two different IP addresses: one for its connection to the LAN and the other for the WAN or the Internet. The router presents a single address to the Internet that represents all the computers and other devices on your LAN; it performs a function called network address translation (NAT) that converts your public address to the addresses of individual network devices.
