मुफ्त ऑनलाइन कोर्स Operating Systems Interview Prep and Placements Course

कोर्स का विवरण

Prepare for operating systems interviews and placement rounds with a free, structured course designed for Information Technology learners focused on Hardware and OS. Build a clear foundation in core OS concepts and connect theory to practical understanding that interviewers expect.

Start with the essentials, including what an operating system is, common types, key components, multitasking vs multithreading, boot process, system calls, and important architecture and storage comparisons. Move into processes and scheduling with topics like process creation, process states, context switching, schedulers, and classic CPU scheduling strategies such as FCFS, SJF, priority scheduling, round robin, multilevel queue, and MLFQ, including how to compare them in real scenarios.

Strengthen your grasp of concurrency through critical sections, race conditions, conditional variables, and the most asked synchronization problems, including producer-consumer, reader-writer, and dining philosophers. Learn deadlocks from definitions and necessary conditions to avoidance, detection, recovery, and practical problem solving with interview-style coding practice.

Finish with memory management fundamentals and advanced concepts such as contiguous allocation, free space management, paging, segmentation, virtual memory, page faults, page replacement strategies including LRU implementation ideas, and thrashing. Ideal for candidates who want a focused OS roadmap for interviews with concept clarity and problem-solving confidence.
