Answer / Narander Singh
A deadlock is a situation that occurs in concurrent programming, including databases like Oracle, where two or more processes are blocked and waiting for each other to release resources required for progress. This usually happens when one process holds a resource needed by another process, while the second process holds a resource needed by the first. As both processes wait for the other to release resources, they remain in an infinite loop, leading to a deadlock.
