Example text

Whereas switches have ports into which individual hosts plug, routers have interfaces to which LAN segments attach. In simple terms, a router’s job is to move packets of data between attached LAN segments. The router is the single most important type of device in internetworking. It provides the flexibility and decision-making power that make it possible to run complicated internetworks. Without the logical capability routers provide, the Internet would be hundreds of times slower and much more expensive.

A normal router can be programmed to perform many of the basic duties that a firewall can perform, but a device that only does access lists, network address translation, and port blocking should never be confused with a true firewall. To ensure a much higher level of security, a dedicated firewall device is highly recommended in most instances. Furthermore, firewalls capable of performing stateful inspection, along with intrusion prevention, are generally required to properly safeguard assets from potential threats.

But at the heart of Cisco’s products and technologies are its switches and routers—and we haven’t shoved them aside for the new stuff. Of course, all the chapters were updated to cover the latest hardware and software offerings from Cisco. So what’s the reason for all of this work and revision? We continue to think there is an enormous need by networking professionals for a clear, concise introduction to Cisco and its technologies. What is truly needed is a simple understanding of networking and Cisco’s role in networking to make sense of many IT issues.
