What is safe state in os?

In operating systems, a safe state refers to a condition in which the system can allocate resources to processes in such a way that all processes can complete their execution without leading to a deadlock. Specifically, a system is considered safe if there exists a sequence of processes that can finish executing with the available resources. If a system is in a safe state, it can guarantee that resource allocation will not lead to potential deadlock situations. Conversely, if no such sequence exists, the system is in an unsafe state, which may lead to deadlock.
