Final answer:
To perform an activity blocked by a resource lock, you must wait until the lock is released. Synchronization mechanisms like locks, semaphores, or monitors can be used in programming to implement resource locks.
Step-by-step explanation:
If an activity is blocked by a resource lock, it means that another process or thread is currently using the resource and has exclusive access to it. To perform the activity, you would need to wait until the resource lock is released. In programming, this can be done using synchronization mechanisms like locks, semaphores, or monitors.
For example, let's say you have a program that needs to write data to a file, but the file is locked by another process. By implementing a resource lock, you can ensure that the file is not accessed by multiple processes simultaneously, avoiding data corruption.
Once the resource lock is released, the blocked activity can proceed, and you can perform the necessary operations on the resource.
