What does inter-process communication (IPC) allow processes to do?

• A. Access shared files concurrently.
• B. Communicate and synchronize their actions.
• C. Execute independently without interaction.
• D. Manage their own resources independently.

Answer: (B)

Inter-process communication (IPC) is a fundamental mechanism used by operating systems that enables processes to exchange data and synchronize their actions. By facilitating communication between processes, IPC allows them to work together effectively, sharing information and coordinating tasks. For instance, two processes might need to collaborate to complete a larger task, where one process produces data that another process uses. IPC encompasses a variety of methods, such as message passing, shared memory, pipes, and sockets, providing the means for different processes to pass messages, signals, or data efficiently. This collaboration is crucial in multi-process environments where tasks need to be synchronized, ensuring that processes can operate in harmony while adhering to the system's concurrency model. While concurrent access to shared files and independent execution of processes may also be components of system operation, they do not embody the role of IPC, which specifically involves communication and synchronization between processes. The essence of IPC lies in its ability to enable interaction, making the processes more interdependent rather than operating completely in isolation.
