Explain deadlock and its conditions.

Semaphore vs Mutex

Accepted Answer

Deadlock is a situation where two or more processes are unable to proceed because each is waiting for the other to release a resource.

Deadlock occurs when two or more processes are stuck in a circular wait, where each process is waiting for a resource held by another process.
The four necessary conditions for deadlock are mutual exclusion, hold and wait, no preemption, and circular wait.
Synchronization refers to the coordination of multiple processes or threads to ensure their orderly execution and prevent race conditions.
Paging is a memory management technique where the operating system divides the physical memory into fixed-size blocks called pages.
Semaphore and mutex are both synchronization mechanisms, but a semaphore can allow multiple threads to access a resource simultaneously, while a mutex allows only one thread at a time.
