A deadlock is a state in a computer system where two or more processes are unable to proceed because each is waiting for the other to release a resource. This impasse leads to a standstill in the execution of programs, resulting in a halt of system operations. Deadlocks typically occur in multitasking or multi-process environments, where processes compete for shared resources such as memory, files, or hardware devices.
The deadlock scenario involves a cyclic waiting condition, where each process holds a resource and waits for another resource held by a different process. This circular dependency prevents any of the involved processes from making progress, causing the entire system to become unresponsive.
Key conditions for a deadlock to occur include mutual exclusion, where resources cannot be simultaneously shared; hold and wait, where a process holds resources while waiting for additional ones; no preemption, where resources cannot be forcibly taken away from a process; and circular wait, where a cycle of processes forms, each waiting for the next to release a resource.
Deadlock prevention and resolution strategies are crucial in system design to ensure efficient resource utilization and prevent the potential negative impacts of deadlocks on overall system performance.A deadlock is a state in a computer system where two or more processes are unable to proceed because each is waiting for the other to release a resource.
