Additional Activities

The additional activities for this week are:

Activity 2:1: Match the Layer

In this activity you should drag the term used in the red boxes at the bottom of the exercise, and place it in correct layer of the OSI model. Practice the exercise, and determine your lowest time to complete the exercise. [Link]


Activity 2:2: Match the Protocol

In this activity you must pick up the network protocols which are defined in the brown boxes, and place them in the correct layer of the OSI model. Practice the exercise, and determine your lowest time to complete the exercise [Link]


Activity 2.3: Test

Please conduct the following test which is based on Unit 2. [Link]


Activity 2.4: Broadcast Domains

Repeaters and hubs operate a Layer 1, and forward collisions and broadcasts.

Bridges and switches operate at Layer 2, and forward broadcasts, but block collisions.

Routers block both collisions and broadcasts.

Complete the following activity, by locating the broadcast domains [Link]


The challenge for this week is:

Challenge 1

A break in a cable will cause a digital pulse to be reflected off the break and return to the source. In this challenge you will be told the time it takes a pulse to reach a break and return to the source, and you must determine where the break in the cable is. After you calculate your result, please submit your answer [Link]
