Lecture

Networking Lesson Plan Week 2 Addendum


Teaching Methodology and Internal Components



As a teacher, I have to figure out what I want you to learn, what it is that you know or think you know, and then how to get you from here to where I want you. I have determined that to demonstrate competencies in this class, you need to know the following areas:


Design of a network

How to build a network

How to connect computers from a hardware point of view

How to configure the software necessary

How to set up a server to include

DHCP

DNS

Web Services

Mail

File Servers

Print Server

Streaming Media

Chat

Instant Messaging

FTP

Newsgroups (blogging)

SNMP

Storage area Networks

Client/server applications

User Accounts

Security

Mapping Network Drives

Net use Commands

Directory Services (Active Directory)

Subnetting

Routing

How to configure routers and switches

How to build network cables

How to build the network in a real house

To understand networks is to understand computers. The job of a network technician is almost indistinguishable as a computer technician. Therefore we will start this lesson with an internal components lecture about the computer.

We will build the classroom network multiple times until everyone can setup the routers and servers in their sleep. The text we use is fairly top level but we will supplement that with the CCNA course that used to be taught here.


Internal Components Lecture


Distribute motherboards to each student.


Explain Rear connectors:




CPU – Central Processing Unit


Locate CPU on motherboard. Explain about number of wires between CPU, memory, buses, and disk drives.


Expansion bus types:

ISA - 8 bit (8 wires to CPU)

EISA -16 bits

PCI - 32 bits

AGP - 32 bits


Show bus wires on motherboards. Enter introductory explanation of binary numbering system. Explain how many wires are available is what determines how many memory addresses are available. Show exponents and review the math required for understanding of binary numbers. Also show how disk drives have more space than is logical according to the math. Leave open ended as to why this is.



Show Diagram of CPU-Memory-bus-disk drive connection



Go into in depth discussion of binary and addressing math.


Talk about Chip sets:



Remind students they need to know this for Certification tests but will not ever change on in the field – not field replaceable.


Talk about storage: Volatile vs. non-volatile


Permanent storage devices – disk drives, cd’s, other devices


Temporary storage ram sticks


Types of Ram:


Simm – Single inline memory module

30 pin and 72 pin styles – not much in use anymore

Dimm – Dual inline memory module

168 pin SDRAM – synchronous dynamic random access memory

184 pin DDR SDRAM – double data rate synch dyn ram

184 pin DDR2 SDRAM really fast

Rimm – Rambus inline memory module


Types of Dimm -



EIDE devices – up to 4 on a motherboard



Basic Electronics


Show diagram of closed circuit – add switch – add resistance


Go into discussion of power connections and formulas and conversions


Introduce voltmeter


Demonstrate voltmeter
