Discussion 4

1"Comparing Approaches "  Please respond to the following:

• A) Outline the primary ways in which the traditional approach to modeling a use case differs from an object-oriented approach. Develop a scenario in which you would use the traditional approach over the object-oriented approach, and explain your reasons why.

• B) Analyze the difference between a use case and a scenario. Give a specific example of a use case with at least two (2) possible scenarios.

2"Cache Memory and Multicore Processors" Please respond to the following:

• A) From the e-Activity (Use the Internet to research the type of cache memory (Level 1, Level 2, or another type) that is on a computer you own or a computer that you would consider purchasing. Be prepared to discuss. Note: You can usually obtain this information from the computer manufacturer’s Website), determine the type of cache memory (i.e., Level 1, Level 2, or another type) that resides on a computer that you own or on a computer that you would consider purchasing. Examine the primary manner in which the type of cache memory that you have identified interfaces with the CPU and memory on your computer. Determine which type of cache memory is the most efficient, and provide one (1) example that depicts the manner in which the use of one (1) type of cache memory makes your computer processing more efficient than another.

• B) Evaluate the advantages and disadvantages of both symmetrical and master-slave multiprocessing systems in regards to computer processing speed, multiprocessing configuration, overheating, and cost. Of the two (2), recommend the type of processor that would be better suited for a computer that is primarily used for the following: Word processing, Microsoft Excel spreadsheets, and computer gaming. Provide a rationale for your response.
