those factors that limit the business to grow, hence reduce the chance of

generating profit. One of the best ways to evaluate the opportunities and

constraints is to conduct Strengths, Weakness, Opportunities and Threats

Task: Create your own Ethernet Cable

Directions: Prepare the following tools and materials in fabricating your own

cross over and straightthrough cables.

Materials:

1) 6 meters Ethernet Cable Category 5e or Cat5e- standard wire for

cabling;

2) RJ45 crimpable connectors for Cat5e;

Tools:

3) RJ45 Crimping tool;

4) Wire cutter, stripper or pliers; and

5) Ethernet cable Tester / LAN Tester

Take Note: Be careful when using the tools.

You just need to follow the procedures cited in this module and apply

the safety precautions to avoid injury or any unwanted incident. You will be

given 30 minutes to complete the task. You will be rated according to the

performance rubric.

Procedures:

1. Cut into the plastic sheath 1 inch from the end of the cut cable. The

crimping tool has a razor blade that will do the trick with practice.

2. Unwind and pair the similar colors.

3. Pinch the wires between your fingers and straighten them out as

shown. The color order is important to get correct.

4. Use scissors to make a straight cut across the wires 1/2 Inch from the

cut sleeve to the end of the wires.

5. Push the wires into the connector. Note the position of the blue plastic

shielding. Also note how the wires go all the way to the end.

42

6. A view from the top. All the wires are all the way in. There are no short

wires.

7. Crimping The Cable – carefully place the connector into the Ethernet

Crimper and cinch down on the handles tightly. The copper splicing

tabs on the connector will pierce into each of the eight wires. There is

also a locking tab that holds the blue plastic sleeve in place for a tight

compression fit. When you remove the cable from the crimper, that end

is ready to use.

8. For a standard "Straight Through" cable, repeat all steps and wire color

order on the other end of cable. For a cross-over cable, the other end

will have a different color order as shown by the crossover picture

above.

9. Make sure to test the cables before installing them. An inexpensive

Ethernet cable tester does this quite well.

In order to validate their performance, the teacher must construct a rubric appropriate to the activity.

Task: Configure Windows XP Firewall

Direction: In this laboratory activity you will explore the Windows XP Firewall and configure some advanced settings. There are essential questions that you need to answer while performing the activity.

Step 1

Navigate to the Windows XP Firewall:

Start > Control Panel > Security Center

The Firewall indicator shows the status of the firewall. The normal

setting is “ON”.

Access the controller for the firewall by clicking Windows Firewall at

the bottom of the window.

Step 2

52

Essential Questions:

In the space below, state why turning off the Windows Firewall is

not advised.

Step 3

From the Windows Firewall control menu select the Exceptions tab.

Programs and services that Windows Firewall is not blocking will be

listed with a checkmark.

You can add applications to this list. This may be necessary if your

customer has an application that requires outside communications but

for some reason the Windows Firewall cannot perform the

configuration automatically. You must be logged on to this computer as

an administrator to complete this procedure.

53

Essential Question:

Creating too many exceptions in your Programs and Services file

can have negative consequences. Describe a negative consequence of

having too many exceptions. _______________________________________________________________________

_______________________________________________________________________

_______________________________________________________________________

Step 4

From the Windows Firewall control menu select the Advanced tab to

view the Network Connection Settings. Network Connection

Settings displays the different connections configured for your

computer.

Step 5

There are many applications that users do not normally see that also

need to get through the Windows Firewall to access your computer.

These are the network level commands that direct traffic on the

network and the Internet.

54

Under the ICMP heading, click the Settings button. You will see the

menu where ICMP exceptions are configured.

In the example here, allowing incoming echo requests is what allows

network users to “ping” your computer to determine if it is present on

the network and how fast information travels to and from it.

Essential Question:

In the space below, list the requests for information that your computer will

respond to. _______________________________________________________________________

Testing Network Connection with Ping Symptoms:

Guide the students in doing the activity on pages 297-299.

Demonstrate the Ping Command

wants to test the network using Ping

wants to test the latency of the network

1. Open the Command Prompt or Terminal. Every operating system has

a command line interface that will allow you to run the Ping command.

The Ping command operates virtually identically on all systems.

o If using Windows, open the Command Prompt. Click the Start

button and enter "cmd" into the Search field. Windows 8 users can

type "cmd" while on the Start screen. Press Enter to launch the

Command Prompt.

Enter key to execute the command. Here is a brief explanation of

commonly used ping commands:

o ping 127.0.0.1 (This is a "loopback ping" - your computer trying to talk

to itself. If the loopback step fails, it might be because the TCP drivers

are corrupted, the network adapter might not be working, or another

service is interfering with IP.)

o ping <IP address> (This will ping the IP address of a device like a local

computer, remote server or any client that receives an IP address to

verify that it is reachable and that you can communicate with it

properly.) Example: ping 192.168.1.1 (this is the default IP address of

NETGEAR routers)

o ping<website address> (This command will test for the Internet

connectivity and DNS functionality.) Example: ping www.netgear.com,

ping google.com
