As the chief engineer at a highly successful operating systems company, you must make tough choices regarding engineering tradeoffs every day. As a former Linux administrator, your goal is to make the lives of other administrators easier while ensuring the company’s operating systems can be easily configured to meet new business needs.
Your engineering team wants to make architectural changes to the company’s customized distribution of the Linux operating system—specifically, the memory allocation mechanism used by the kernel. The team wants you to weigh in by giving them guidance on two important areas of memory management.Choose one of the two positions below and provide a well-researched and technically accurate answer. (Note: Choose positions that have been least addressed by your classmates.)
- Position 1: Explain how memory managed as separate address spaces provides memory protection for multiple processes. Is this model more or less complex than having all processes use the same memory space? Are there security concerns?
- Position 2: Explain the benefit of using memory allocation data structures composed of linked lists. Address the concepts of first, best, and quick fits. Are there other data structures that would be more suitable? Given that Linux is open source, does the administrator of a Linux system have the option of selecting another memory allocation architecture?
After your initial post, respond constructively to two of your peers’ posts by analyzing their initial posting for the clarity and technical accuracy of their explanations and the quality of their research.

Graduate Discussion Rubric
Overview
Your active participation in the discussions is essential to your overall success this term. Discussion questions will help you make meaningful connections
between the course content and the larger concepts of the course. These discussions give you a chance to express your own thoughts, ask questions, and gain
insight from your peers and instructor.
Directions
For each discussion, you must create one initial post and follow up with at least two response posts.
For your initial post, do the following:
Write a post of 1 to 2 paragraphs.
In Module One, complete your initial post by Thursday at 11:59 p.m. Eastern.
In Modules Two through Ten, complete your initial post by Thursday at 11:59 p.m. of your local time zone.
Consider content from other parts of the course where appropriate. Use proper citation methods for your discipline when referencing scholarly or
popular sources.
For your response posts, do the following:
Reply to at least two classmates outside of your own initial post thread.
In Module One, complete your two response posts by Sunday at 11:59 p.m. Eastern.
In Modules Two through Ten, complete your two response posts by Sunday at 11:59 p.m. of your local time zone.
Demonstrate more depth and thought than saying things like “I agree” or “You are wrong.” Guidance is provided for you in the discussion prompt.
