Understanding Deadlocks in Operating Systems

Deadlocks in operating systems occur when processes hold resources and wait for others, leading to a state where none can progress. Processes may hold resources while requesting more, resulting in a standstill known as a deadlock. This deadlock arises from conditions like mutual exclusion, hold and
