There are certain conditions that have to occur for a deadlock. They are as follows: 1. Mutual Exclusion This means that resources can be used in a mutually exclusive way. So, two processes will not be able to access the same resource at a particular point in time. At least one resourc...

for a deadlock to occur, four conditions, known as the coffman conditions, must be met simultaneously: mutual exclusion, hold and wait, no preemption, and circular wait. how does mutual exclusion contribute to deadlock? mutual exclusion, a key factor in deadlock scenarios, arises when ...

Many OS course textbooks will cite the four conditions necessary for a deadlock to occur: A limited number of a particular resource. In the case of a monitor in C# (what you use when you employ the lock keyword), this limited number is one, since a monitor is a mutual-exclusion lock ...
