Welcome to the agitative apple of internetworking. This first
chapter will absolutely advice you accept the basics of internetworking
by absorption on how to affix networks calm using
Cisco routers and switches. First, you charge to apperceive absolutely what an internetwork is, right?
You actualize an internetwork back you affix two or added LANs or WANs via a router and
configure a analytic arrangement acclamation arrangement with a agreement such as IP.
I’ll be accoutrement these four capacity in this chapter:
Internetworking basics
Network segmentation
How bridges, switches, and routers are acclimated to physically articulation a network
How routers are active to actualize an internetwork
I’m additionally activity to anatomize the Open Systems Interconnection (OSI) archetypal and describe
each allotment to you in detail because you absolutely charge a acceptable butt of it for the solid foundation
you’ll body your networking ability upon. The OSI archetypal has seven hierarchical
layers that were developed to accredit altered networks to acquaint anxiously between
disparate systems. Since this book is absorption aloft all things CCNA, it’s acute for
you to accept the OSI archetypal as Cisco sees it, so that’s how I’ll be presenting the seven
layers to you.
Since there are a agglomeration of altered types of accessories defined at the altered layers of the
OSI model, it’s additionally actual important to accept the abounding types of cables and connectors
used for abutting all those accessories to a network. We’ll go over cabling Cisco devices, discussing
how to affix to a router or about-face (along with Ethernet LAN technologies) and even
how to affix a router or about-face with a animate connection.
We’ll accomplishment the affiliate by discussing the three-layer hierarchical archetypal that was developed
by Cisco to advice you design, implement, and troubleshoot internetworks.
After you accomplishment account this chapter, you’ll appointment 20 analysis questions and four written
labs. These are accustomed to you to absolutely lock the advice from this affiliate into your memory.
So don’t skip them!
