Assignment Questions

 

Question No. 1:                                 (5 marks)

Some scenarios are given in column A, you need to find the corresponding computer model or type of simulation model from column B and write the correct answer into Column C.

 

A

B

Answer (C)

A simulation model for a car journey was created where the interest is on the speed of the car throughout the journey

INET

 

Overlay and peer-to-peer network simulation framework

Continuous simulation model

 

Offers models for MAC protocols

Deterministic 

 

A model’s behavior is entirely predictable

Question No. 2:                                                                  (5 marks)

Ahmad is a social media influencer, decides to open a new page and his target is to reach 5k followers in 5 days. As per his past experience, he assumes that each day he will get 1.5 k new followers that had never followed the page and of his current followers he believes 5% will stop following the page each day. However, 10% of those that left the page in the past will join again each day. 

 

Considering the above scenario, answer the following question:

According to your understanding, which type of computer model can be constructed to reach the target? Justify your answer with valid reason.

 

 

Question No.3:                                                             (5 marks)

Ayesha is an IT expert and knows that “a simulation can use repeated sampling to obtain the statistical properties of some phenomenon (or behavior)”, now she has assigned a task to develop a simulation for the following situation:

“Pour a box of coins on a table, and then compute the ratio of coins that land heads versus tails.”

Which type of simulation will be used here to determine the behavior of repeated coin tosses? Justify your answer with valid reason.
