Assessment

 Rubric for Lab Worksheet

 

_____ (of 1) – Vocabulary Terms

            Score 1:    3 of 4 terms are defined adequately.

            Score 0:    Less than 3 terms adequately defined

 

_____ (of 5) – ping results excluding hop-count

            Score 5: complete data for 5 or more ip addresses

            Score 4: 5 or more ip addresses, but incomplete data provided

            Score 3: data incomplete; 3 or more ip addresses

            Score 0: no results provided

 

_____ (of 2) – hop-count

            Score 2: hop-count provided from tracert

            Score 0: missing hop-count

 

_____ (of 2) – Conclusions  

Sample Factors Affecting Speed:

·         Type of access (i.e., bandwidth): cable, DSL, dial-up

·         Proximity of ISP to internet backbone (# hops)

·         Volume of data sent

·         Congestion on net due to other traffic (varies with time)

·         Individual router/server very busy

·        Size of target computer + volume of other traffic

            Score 2: Student has listed 3 or more factors that could

affect speed.

Score 1:  Student has listed 1 or 2 plausible factors.

            Score 0: Student has listed no plausible explanations.
