Q2) Explain how the universal use of the Web has changed software systems.  

Q3) To help counter terrorism, many countries are planning or have developed computer systems that track large numbers of their citizens and their actions. Clearly this has privacy implications. Discuss the ethics of working on the development of this type of system.  

a. Explain the notion of “crypto system;” also, say how its encryption and decryption 

algorithms can be specified mathematically.

b. Biometric technology has been available for a number of years; however, its adoption has 

been slow. Discuss the factor(s) that you see as inhibiting or delaying the adoption of biometric 

technologies. Also include in your answer any factor(s) that might increase the adoption of

Consider a client approached you to design and develop a Vacation Home Rental Online Marketplace (VHROM) for them so that a large number of customers & providers can interact and make transactions.

Task-2:

a) In order to manage the project efficiently divide the project into tasks, estimate duration for each task to be completed and define if there are task dependencies. Based on this produce a task, duration dependency table.

b) In order to track progress of your project, create an activity Bar chart to plot your task, milestones and dependencies against time.

c) In order to manage your staff in a better way, prepare a staff activity chart as per estimated number of staff required for the project.
