IT Essentials 

Chapter 7:  Networking Concepts 

 

Section 7.0 

This first section introduces the topics to be covered in the chapter. 

 

Section 7.1 

This section introduces some basic principles of networking and includes network media and 

the basic types of networks such as LANs, MANs and WANs.  The differences between a peer‐

to‐peer and a client/server network are discussed.

 Section 7.2 

Section 2 begins with an introduction to standards organizations.  On page 7.2.1.1 each 

standard icon is a hyper‐link to that organization’s home page.  Follow each link to obtain more 

information regarding the organization.  Protocols and the networking reference models are 

covered next.  Both the OSI model and the TCP/IP model are key concepts in networking: 

 

 

Page 7.2.1.4 contains protocol information with reference to the TCP/IP model.  The section 

continues with describing protocol data units (PDU’s) and the process of encapsulation.

 Section 7.3 

This section gives an overview of some of the main components in a network such as modems, 

hubs, bridges and switches.  This topic includes an introduction to cables.   

Page 7.3.2.7 introduces a Cisco made network simulation program called “Packet Tracer”.

 The assignment here is to first download and install Packet Tracer (PT) version 7 from the Cisco 

Networking Academy web site.   Then open both the PDF for directions, and then the PT file.  

Follow the directions in the PDF and complete the file.  Submit only the PT file for grading. 

Fiber cables have two main types: 

Single Mode Fiber  Multimode Fiber 

   

 

Section 7.4 

Network addressing is covered here and includes: 

MAC addressing
