You will be including revised content from this interactive assignment in your OS Theory Concept Map final assignment. Prior to completing work on this interactive assignment, you may wish to review the instructions included for the OS Theory Concept Map final assignment in Week 5 to see how it fits into your overall final project. To complete this week’s interactive assignment, you will continue building the OS Theory Concept Map by addressing the following topics concerning how operating systems enable processes to share and exchange information: Describe process, process state, and process control block. Compare single- and multi-threaded motivations and models. Describe the critical-section problem and explain a software solution that resolves this problem. Logically arrange the essential concepts about threads and process synchronization into a hierarchy of nodes that branch from the main idea. Include cross-links where necessary to show relationships in different sections of the concept map. Use connecting nodes to accurately describe each relationship between topics that connect. Section 2 must have at least three nodes and four connecting nodes. After completing Section 2 of the concept map, post a link to your OS Theory Concept Map in the discussion forum for your peers to review.
