1. Describe the heuristic used in menu option 2.
2. Provide an example or define the characteristics of a situation where this heuristic would be efficient. In this context, efficient, means a situation where required the data can be supplied from the buffer and not from an external source such as the disk. A hint is to look at what data occurs most frequently. In this case it is the value 5.
For option 3 on the menu (LFU), run the algorithm twice and observe how the algorithm responds. For the first iteration of this option use the following input:
Buffers: 2
Pages: 6
Page Values: 5, 10, 5, 10, 20, 5
For the second iteration of this option use the following input:
Buffers: 2
Pages: 6
Page Values: 5, 10, 20, 25, 30, 35
Questions Goup_3: (Answer these questions)
1. Describe the heuristic used in menu option 3.
2. What happens when no integer is repeated in the input page values?
3. Describe what happens in the buffer pool when a value is repeated in the page values.
Complete the preceding exercise and develop a response to each of the questions. Post your responses to the discussion forum. If you have arrived at a different answer or analysis than your peers, discuss your findings with your peers and attempt to determine whose analysis is most accurate.
Part_2-) Learning Journal (Do this in 4 pages followed by its own references)
The paper must cite a minimum of one source in APA format and be well-written
________________________________________
The Learning Journal is a tool for self-reflection on the learning process. In addition to completing directed tasks, you should use the Learning Journal to document your activities, record problems you may have encountered and to draft answers for Discussion Forums and Assignments. The Learning Journal should be updated regularly (on a weekly basis), as the learning journals will be assessed by your instructor as part of your Final Grade.
Your learning journal entry must be a reflective statement that considers the following questions:
• Describe what you did. This does not mean that you copy and paste from what you have posted or the assignments you have prepared. You need to describe what you did and how you did it.
• Describe your reactions to what you did
• Describe any feedback you received or any specific interactions you had. Discuss how they were helpful
• Describe your feelings and attitudes
• Describe what you learned
Another set of questions to consider in your learning journal statement include:
• What surprised me or caused me to wonder?
• What happened that felt particularly challenging? Why was it challenging to me?
• What skills and knowledge do I recognize that I am gaining?
• What am I realizing about myself as a learner?
• In what ways am I able to apply the ideas and concepts gained to my own experience?
• Finally, describe one important thing that you are thinking about in relation to the activity
