Disclaimers

If you found a mistake (sorry!) or know a better way of doing/explaining something or if you think I may have missed out something important, please post an issue or submit a pull request! 😊

This repo is an assimilation of knowledge from various sources that I didn't completely keep track of when I was learning. So, if you found a resource I might have referenced and paraphrased (or straight up regurgitated) in this repo, please do let me know and I would be happy to add it to the growing list of references.

techinterview's Issues

Semaphore vs Mutex

Great Collection! πŸ’―

But in https://github.com/SuyashLakhotia/TechInterview/blob/master/5%20-%20OS%20Fundamentals.md#mutexes--semaphores you've mentioned that "They differ only in that a semaphore's integer may start at a number greater than 1."

I don't think it's that accurate because a mutex is locking mechanism used to synchronize access to a resource, while Semaphore is signaling mechanism (β€œI am done, you can carry on” kind of signal).

Let me know if I'm wrong :)
