answer the questions based on the scenarios: Question $6$: Concurrency and Synchronization; Your operating system supports multi$-$threaded applications, but users have reported occasional data corruption and application crashes. How would you address these issues related to concurrency and synchronization? Question $7$: : Influences of Security, Networking, Multimedia, Windows Question: A multimedia company is developing a new video editing software that requires high performance and secure handling of multimedia files. $1.$ Explain how the operating system can influence the performance and security of the video editing software. $2.$ Discuss the role of networking in the context of collaborative video editing and how the operating system can support this functionality. $3.$ Identify potential security threats to the video editing software and propose solutions to mitigate these threats. Question $8$: Distributed System; You are tasked with managing a network of servers in a data center. One server in the cluster is experiencing high traffic, while others are underutilized. How would you optimize resource allocation in this distributed system? Question $9$: Structuring Methods $($Monolithic$,$ Layered, Modular, Micro$-$Kernel Models$)$ Question: A tech startup is evaluating different operating system architectures for their new IoT device. $1.$ Compare the monolithic, layered, modular, and micro$-$kernel models in terms of their structure, performance, and maintainability. $2.$ Recommend the most suitable architecture for the IoT device and justify your choice. $3.$ Discuss the potential challenges in implementing the chosen architecture and propose solutions to address them. Question $10$: Abstractions, Processes, and Resources Question: A cloud service provider is designing a new operating system to manage virtual machines and resources in their data centers. $1.$ Explain the abstractions that the operating system should provide to manage processes and resources in a cloud environment. $2.$ Discuss how the operating system can ensure efficient resource allocation and load balancing across multiple virtual machines. $3.$ Propose mechanisms to handle resource contention and ensure fair resource distribution among virtual machines.
