Define and Explain the Symmetric Multiprocessors (SMP) and explain both its characteristics and Advantages. Describe and Explain the abstraction of Computer Hardware, Operating System, and Software Structure. Describe and Explain the Memory Layout for a Resident Monitor. Compare in detail between the Batch Multiprogramming versus Time Sharing. List with a brief explanation the Causes of Errors in operating system design and implementation some errors may occur. What are the Components of a Process? In Memory Management, the OS has five principal storage management responsibilities. List them and briefly Explain the five principal storage management responsibilities. Briefly Explain: How does the Virtual Memory Addressing work? Briefly Explain: What are the Main issues for Information Protection and Security of an OS? There are two approaches of OS Design, a Distributed Operating System and Object-Oriented Design. Explain both approaches and what do you suggest to improve OS Design. What is Fault Tolerance? A multiprocessor OS must provide all the functionality of a multiprogramming system plus additional features to accommodate multiple processors. Briefly explain the Key design issues of OS Symmetric Multiprocessor.
