Master the fundamental concepts and design principles of operating systems through this comprehensive course covering essential topics for computer science and electronics students. Explore how operating systems function as intermediaries between users and computer hardware, providing environments for convenient and efficient program execution. Learn about operating system structures, services, and interfaces, including system calls, system programs, and virtual machines. Dive deep into process management concepts including process states, control blocks, scheduling, context switching, and interprocess communication through shared memory and message passing systems. Study threading fundamentals, multithreading models, hyperthreading, and threading issues including fork() and exec() system calls. Examine CPU scheduling algorithms such as First Come First Served (FCFS), Shortest Job First (SJF), Priority Scheduling, Round Robin, and multilevel queue scheduling with practical problem-solving examples. Understand process synchronization challenges including the critical-section problem, Peterson's solution, semaphores, and classic synchronization problems like bounded buffer, readers-writers, and dining philosophers. Explore deadlock concepts, prevention, and resolution strategies. Investigate memory management principles covering main memory allocation and virtual memory systems. Study storage management including file system interfaces, implementation strategies, mass storage structures, and I/O systems. Learn about protection and security mechanisms in operating systems. Examine distributed systems concepts including distributed system structures, file systems, and coordination mechanisms, along with special-purpose system considerations.
