Suppose the daytime processing load consists of 60% CPU activityand 40% disk activity. Your customers are complaining that thesystem is slow. After doing some research, you learn that you canupgrade your disks for $8,000 to make them 2.5 times as fast asthey are currently. You have also learned that you can upgrade your CPU to make it 1.4 times as fast for $5,000.
a) Which would you choose to yield the best performance improvementfor the least amount of money?
b) Which option would you choose if you don't care about the money,but want a faster system?
c) what is the break -even point for the upgrades? that is , what price would we need to charge for the CPU (or the disk -change only one) so the result was the same cost per 1% increase for both?
Recognize a particular website that you frequently go to and explain targeted audience that goes to that particular site. Do not say "everyone" since all sites always have general target audience.
Then calculate message digest on the result. Would this be a good message digest function? Describe. Message digests are reasonably fast.

Consider a simple paging system with the following parameters: 2^32 bytes of physical memory, page size of 2^10 bytes, and 2^16 pages of logical address space. How many bits are in a logical address?
All of the following are events except: a macro running in response to a form button being clicked, changing the data in a cell, clicking on a control button or opening or closing an Excel workbook.
For random geometric graph, G(n, r), evaluate average degree of a vertex: at least distance r from boundary, on boundary (convex hull), and estimate time (big Oh) of determining all edges employing: all vertex pairs testing.
Explain a business scenario and specify the types of constraints that would be appropriate to make sure the integrity of the database. For example, an airline reservation system should not make a reservation.
