01-Apr-2023Deadlock is a situation that can occur in a multi-process system where two or more processes are blocked, waiting for each other to release the resources they hold, resulting in a standstill of the system. In other words, a deadlock is a state where a group of processes is all blocked and none of them can proceed.
For a deadlock to occur, four necessary conditions must be satisfied simultaneously. These conditions are as follows:
If all of these conditions are satisfied, then a deadlock will occur. Breaking any one of these conditions can prevent a deadlock from occurring.
