Q. List three instances of deadlocks that aren't related to a computer system environment.

Answer:

• Two cars passage a single-lane bridge from opposite directions.
• A person going down a ladder even as another person is climbing up the ladder.
• Two trains travelling toward each other on the same track.
• Two carpenters who should pound nails. There is a single hammer as well as a single bucket of nails. Deadlock takes places if one carpenter has the hammer and the other carpenter has the nails.
