A) For the given network diagram, suppose an application running on Host 1 transmits a packet towards application running on Host 2. Graphically represent the process of packet encapsulation and de-capsulation along the path from Host 1 to Host 2. b) Both Layer-2 Switch and Router are used to forward network traffic from one interface to another. How are they different in terms of functionality?

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
