These C programs contain the complete solution of the lab assignments I did as part of Operating Systems course at IIITDM Kancheepuram. Some of the most important C programs being,

• My own shell using fork and exec calls in linux OS.
• Solving computational problems like matrix multiplication and magic square using both multithreading using pthreads and multiprocessing using fork system calls.
• Multithreaded implementations using semaphores.
• Proposing and implementing the multithreading and multiprocessing algorithms of traditional Dynamic Programming problems like longest common subsequence problem and so on.
• Solutions of a few classical synchronization problems from The Little Book of Semaphores.
