So here in mutual exclusion situation, only after the printing task is completed then only the next task is processed. For example, the printing process is going on and all sudden another process tries to interrupt the printing process. Where only one processes use one resource at a time only. It means whatever resource we are using it must be used in a mutually exclusive way.

The following are the four important deadlock conditions to occur if all the conditions occur simultaneously there are certain chances for the deadlock to occur. Now if P1 wants to access R2, as we already know R2 is held by P2, and now P2 wants to access R1, which is P1 executes only when it gets accessed to R2, also P2 executes only when it gets accessed to R1 this situation is a deadlock state. car-exampleįor better understanding let us consider another example where there two resources R1, R2, and two processes P1 and P2, where R1 is assigned to P1 and R2 is assigned to P2. But neither of one moves back to allow another car to move forward, this condition is called a deadlock condition. Now the situation arises where Car A driver says he moving towards north is a correct direction, while Car B driver says he moving toward south direction is correct. For instance, let us assume a real-time scenario, where there are two cars A & B, driven by two individual drivers on a one-way road.
