Final answer:
The Readers-Writers Lock allows multiple threads to have simultaneous read-only access to an object protected by the lock. It is commonly used in situations where the majority of operations are read operations and blocking write operations can be limited.
Step-by-step explanation:
The Readers-Writers Lock allows multiple threads to have simultaneous read-only access to an object protected by the lock. This lock is used to manage access to shared resources when multiple threads need to read the data concurrently without causing any synchronization issues.
This mechanism is commonly used in situations where the majority of operations are read operations and blocking write operations can be limited. By allowing multiple threads to read concurrently, performance can be improved in scenarios where data integrity is not compromised.
For example, consider a database system where multiple threads need to fetch data from the database. The Readers-Writers Lock can be applied to ensure that multiple threads can read the data simultaneously, while only one thread can write to the database at a time.
