A deadlock is an undesirable situation or stalemate that occurs when two or more processes are holding
common resources, and each waits for the other to release their resources.
An example of deadlock is where process I has been allocated non-shareable resources A,
e.g., a disk drive, and process 2 has been allocated non-sharable resources B,
e.g., a printer. Now, it it turns out that process
1 needs resources B (printer) to proceed and process 2 needs resource A (the disk drive) to proceed and these are the only two processes in the system, each has blocked the other and all useful work in the system stops.
