Case Study: Multithreading in a Real-Time Vid

You are part of a development team working on a real-time video streaming application. The application needs to handle multiple tasks concurrently, including data collection from video sources, video compression, rendering on the user interface, and network communication. To improve performance and ensure smooth streaming, you decide to implement a multithreaded approach. Multithread Models Selection: Based on the given case study, which multithreaded model (many-to-one, one-to-one, or many-to-many) would you recommend for the threading architecture? Justify your choice considering the nature of tasks such as data collection, video compression, rendering, and network communication. Reg No : 34 to 44

Case Study: System Calls in File Management

Case Study: System Calls in File Management for a Cloud Storage Application You are tasked with developing a cloud storage application where users can upload, download, and manage their files in a secure, multi-user environment. The application will interact with the underlying operating system to perform essential operations like file creation, deletion, reading, and writing. The operating system exposes these functionalities through system calls. System Calls for File Management: In the context of the cloud storage application, identify the system calls involved in file creation, deletion, reading, and writing. Describe how these system calls interact with the file system and the underlying hardware. Reg .No : 55 to 61, 501 -506

Computer System - Elements and organization

Explain the key elements of a computer system, including the CPU, memory hierarchy, input/output devices, and system buses. Discuss the role of the operating system in managing these components. Reg.No : 1 to 11

Evolution of OS

Trace the evolution of operating systems from early batch processing systems to modern real-time and cloud-based OS. Discuss the key milestones, including time-sharing systems, multitasking, distributed computing, and virtualization. Compare different generations of OS in terms of architecture, functionality, and user interaction. How have advancements in hardware influenced OS development? Finally, explore emerging trends such as AI-driven operating systems, edge computing OS, and their impact on future computing. Reg.No : 12 to 22

Processes

Define the concept of a process in an operating system. Explain the different states of a process and how process control blocks (PCBs) manage process execution. Discuss the role of process scheduling in CPU management, detailing the types of schedulers (long-term, short-term, and medium-term) and their functions. Compare various scheduling algorithms such as FCFS, SJF, Round Robin, and Priority Scheduling in terms of efficiency, fairness, and response time. Provide real-world examples where different scheduling techniques are used and analyze their impact on system performance. Reg.No : 23 to 33

Case Study: Inter-Process Communication (IPC)

Imagine you are working on a distributed e-commerce platform where multiple services interact with each other to handle tasks like inventory management, order processing, and payment verification. These services must communicate efficiently to ensure a smooth user experience, especially as the platform scales with increasing traffic and transactions. The platform relies on inter-process communication (IPC) mechanisms to facilitate communication between various services and processes running across different machines in the distributed system. IPC Mechanism Selection: Given the distributed nature of the e-commerce platform, what inter-process communication (IPC) mechanisms (such as message passing, shared memory, pipes, and sockets) would you recommend for communication between services? Justify your choice of IPC mechanism based on factors such as scalability, performance, and security. Reg No : 45 to 55
