The message-passing model allows processes to communicate (A) by sharing a common memory region. (B) by sending and receiving messages through the operating system. (C) by directly modifying each other's memory. (D) through a centralized messaging server. (E) using hardware interrupts.

The operating system executes the memory management for (A) handling the interrupts. (B) improving the system throughput. (C) interprocess communication among two processes. (D) managing user interfaces. (E) storage management.

In most operating systems, communication between independent processes requires the intervention of the kernel to provide protection and the mechanisms needed for communication. However, because threads within the same process share memory and files, they can communicate with each other without invoking the kernel.Group of answer choicesTrueFalse

How do applications and hardware communicate?Applications send requests directly to the hardware, and the hardware sends back a response through the operating system.Operating systems regularly monitor applications and hardware to determine if any common information should be shared between them.Applications and hardware communicate directly, and the operating system interprets this communication to translate it to the user.Applications send requests to the operating system, and the operating system directs those requests to the hardware.

In inter-process communication (IPC), there is a model of message passing. This message passing can be direct or indirect communication. In indirect communication, message passing can be either blocking or unblocking (synchronous or asynchronous respectively). Now elaborate this blocking and unblocking message passing procedure in your own words. Also explain, how producer-consumer problem can be solved by using blocking message passing.
