Question No. 1

Consider an internet service provider which has a large network with idle delay of 5 milliseconds (without any network utilization). Your task is to fill the following table to show the effective delay (in milliseconds) according to Current network utilization and also give the mathematical formula to find out the effective delay according to current utilization.

Current utilization	Effective delay
50%
100%

Formula to find the effective delay (D) according to current utilization ( U)

Question No. 2

Consider a computer network with effective throughput of 2kbits/second; this network is experiencing a delay of 2 seconds. You have to fill in the following table with correct values based on current scenario

Amount of data present in this network (in Kbps)	Formula	Calculation
4kbps	D x T	2 x 2 = 4kbps

SOLUTION:::::::

Consider an internet service provider which has a large network with idle delay of 5 milliseconds (without any network utilization). Your task is to fill the following table to show the effective delay (in milliseconds) according to Current network utilization and also give the mathematical formula to find out the effective delay according to current utilization.

Current utilization	Effective delay
50%	=10 millisecond
100%	= Infinite delay

Formula to find the effective delay (D) according to current utilization ( U)

Question No. 2                                                                                                                                         [5 Marks]

Amount of data present in this network (in Kbps)	Formula	Calculation
4 Kbps	D*T	T*D=4kbps
