Assume you need to download a full HD color image (1920×1080 pixels) What is the required bit rate of the channel?
Now, because you have sufficient usability design experience, you are asked to take on the task of designing a computer. This computer will act as a scanner and a printer. It can also be used as a printer for faxes and copies. It can be installed at home, or in tiny offices.
How are you going to improve the usability problem of such a product? Please draw up a project plan for what kind of process you need to take place, who will be members of your design team, and what kind of methods of design and assessment you plan to implement.
Consider any newly technology which is launched in Pakistan. You have to search all of its features related to design and user usability.
(a) What are the goals and expectations of a typical user while buying a new technology (User Experience Goals)
(b) Based on your research, compare the typical user experience and what features Techno is providing for its users. (Compare Usability and User Experience Goals in your own wording, related to the any new technology you mentioned above.)

You are well familiar with virtual agents. Virtual agents help us search to the web, as e-commerce assistants that give us information about products, as characters in video games, as learning companions or instructors in educational programs, and many more. But there is a website that does not include virtual sales agents but is based on a conceptual model of browsing (e.g., Amazon.com).
I. Is it easy to find information about products on such website?
II. Is any kind of personalization used at the interface to make the user feel welcome or special?
III. Would the site be improved by having an agent? Explain your reasons either way.
IV. Finally, discuss which site (agent based or non-agent based) you would trust most and give your reasons for this.

int fact( int n )
{ if ( n<1 ) return 1;
else
return n*fact(n-1); }
- How much stack space is allocated for “fact” procedure for each call of the procedure, and what register values are they used for?
- If the input is n=1, what is the lowest value the stack pointer attains if the initial value of $sp is 3221225472 ?
- Which registers are used during the execution of “fact” function? Mark the correct choice.
- Explain the stack overflow error when a large n value is input?
