Step 1: Definition of Deadlock.
Deadlock is a situation in operating systems where two or more processes are blocked, waiting for resources held by each other, resulting in a cycle of dependencies. The processes cannot continue because they are each waiting for the other to release resources.
Step 2: Explanation of other options.
- (1) Pooling: Refers to the practice of gathering multiple resources for shared access, not a situation involving blocking.
- (3) Thrashing: Refers to excessive paging and swapping between memory and disk, leading to performance degradation. It is not related to blocked processes.
- (4) Paging: Refers to the technique of managing memory by dividing it into fixed-size blocks, not related to processes waiting for resources.
Step 3: Conclusion.
Therefore, the correct answer is **Deadlock** (2).
