CCNA COURSE CISCO CH 4 ENGLISH

Preparing Network Connections

he first three chapters of this book dealt with
an introduction to networking, networking
concepts, and IP addressing—basically theory
and concept information.
In this chapter, I’ll begin discussing the applied
side of networking. This chapter focuses on installing
your networking devices (switches and routers),
cabling up your LAN and WAN connections,
and establishing a console connection so that you
can put a configuration on these devices.
Once you have established a console connection
in this chapter, Chapter 5 will begin the basics of
using the router’s or switch’s command-line
interface (CLI) to put a basic configuration
on these devices.

IP Addressing

The Transmission Control Protocol/Internet
Protocol (TCP/IP) is a standard that
includes many protocols. It defines
how machines on an internetwork can
communicate with each other.
It was initially funded by and developed
for DARPA (Defense Advanced Research
Protects Agency), which is a conglomeration
of U.S. military and government organizations.
Developed initially for the government, it was
later made available to the public, mainly seen
on Unix systems. First specified in RFC 791,
it has become the defacto standard for
networking protocols. The Internet uses
TCP/IP to carry data between networks,
and most corporations today use TCP/IP
for their networks. This chapter will
provide an overview of TCP/IP, including
some of its more important protocols,
as well as IP addressing.

Networking Concepts

Before considering how to configure Cisco routers
and switches, you must be introduced to basic
networking concepts you’ll need to understand
in order to grasp the advanced concepts discussed
in later chapters. The OSI Reference Model is the
best place to start, since it will help you understand
how information is transferred between networking
devices. Of the seven layers in the OSI Reference
Model, be especially sure to understand how the
bottom three layers function, since most networking
devices function at these layers. This chapter discusses
information flow, as well as Cisco’s three-tiered
hierarchical model, which is used to design scalable,
flexible, and easy-to-troubleshoot-and-maintain
networks.
