Ch. 1 - An Introduction to Networking

Like any textbook, Ch. 1 just eases the reader into the subject! This Ch. 1 begins introducing the vocabulary - "the talk" . You must begin this adventure by knowing the terminology. Already in this Ch. there are over fifty new terms. Don't forget to add the ones I throw in during lectures. Just make a note of any new terms you hear, and we'll include them and define them as we go.

Links that relate to this Ch.:

Looking for high speed "broadband" connectivity to the Internet? Visit here, enter your address and phone exchange number and let this service evaluate who the broadband providers are in your area: http://www.getspeed.com.

Check your  current connection speed.. just go to this link and your speed will be calculated for you:  http://computingcentral.msn.com/topics/bandwidth/speedtest500.asp

Interested in learning more about the Network + Certification sponsored by the Computing Technology Industry Association (CompTIA)? Check this site out and look for the details on the Examination Blueprint. http://www.comptia.org

Networkers of all skill levels have this in common: You have to know  about setting up and using a number of different PCs, both hardware and software.  Here's a resource to look up technical issues regarding PCs and software. Go ahead and sign yourself up, and set up your own profile. You'll know what I mean when you do it! http://www.myhelpdesk.com

Ch. 2 - Networking Standards and the OSI Model

This Ch. identifies the standards organizations and how they work to make the technical aspects of networking  WORK.  In particular, the OSI 7 layer model explains the role of each "theoretical layer" in data transmission.  This is a difficult subject and you will need to be exposed to it multiple times before "the light of understanding" goes on... so start here. We won't beat the subject into the ground here because you'll see it again.... and again... and again!

There are no web sites noted in this Ch., but there's plenty available to further explain this aspect of networking. I suggest you start by checking out some of these sites, and study the one that presents the material in a manner most understandable to you!

Cisco - a leading manufacturer of networking components provides this  free on-line tutorial. It covers a lot of territory, and don't be intimidated by it. Check out the OSI model part for now...    http://www.cisco.com/cpress/cc/td/cpress/fund/ith/ith01gb.htm#xtocid166844

Another Cisco provided resource.. this one says it all about this subject: http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/introint.htm

The gentleman who put this tutorial or "cram notes" used this to prep for the Network + Exam, you can tell from his manner of communicating, this is a difficult subject, but one that must be mastered!     http://www.gis.net/~yagah/nplusosi.shtml

Here's a fairly easy model to follow from fiends in Canada. Check this one out! http://www.echelon.ca/handyman/nettech/index.htm

And one more from a student at Marquette University. I like this one, it's short and can be printed and carried  around and studied conveniently.    http://www.netdatainc.com/braindump/iso-osi.html

Ch. 3 - Network Protocols

This is another "content rich" Ch.. Check out the list of new Key Terms on page 92 of the textbook. Again, don't let this intimidate you. Most of this will make sense soon!  All of it eventually!!


Ch. 4 - Networking Media

Not just about wires, although this a big part of this Ch.. This is the lowest layer of the OSI Model. We'll have some hands on with connectors and cable identification in class.


Thanks to Janice for demonstrating her wiring skills! Thanks also to Angel for assisting in cable making!


Ch. 5 - Network Architecture

Topologies are the physical layout of networks. Some are simple, most are not! Large organizations have topologies that have grown along with their company and number of users. Most networking environments today use the Ethernet transport system. This and Token Ring will be a major area in any networking certification exam.  Again, the vocabulary pages here begin on page 193 and you know the drill on this by now. You should be able to pick the correct term on a multiple choice or true/false test.

This is a good place to start learning about documenting networks.  This years Shareware award for graphics programs goes to Smartdraw for their easy to use graphics program. It's $50 fee is not exactly cheap, but less than other similar programs. A fully functional 30 day trial may be downloaded from http://www.smartdraw.com

Ch. 6 - Networking Hardware

We're really getting into some interesting material here. By the end of this Ch. we will have examined equipment that is represented from layers 1 through 3 of the OSI model.

Cisco has a nice tutorial on LAN devices... take a  look at  their site by clicking here!

Ch. 7 WANS and Remote Connectivity

More about the differences between LANS/ WANS,and different transmission methods.
