What are some real-world examples of shared locks?

Shared locks are commonly used in database management systems. For instance, when multiple users need to read data from a database, a shared lock allows them to do so without interfering with each other.

Can you give me another example?

Sure! In file systems, shared locks can be used when multiple processes need to read a file simultaneously. This ensures that the file remains consistent while allowing concurrent access.

Are there any examples in programming?

Yes! In multithreading, shared locks are used to allow multiple threads to read shared data while preventing write operations until all reads are complete.

What about in real-world scenarios like banking?

In banking systems, shared locks can be used during transactions where multiple users need to view account balances without altering them until the transaction is complete.
