Final answer:
True, blocking primitives in message-passing facilitate efficient and flexible use of computational resources by suspending processes until necessary conditions are met.
Step-by-step explanation:
The statement "Blocking primitives provide for efficient, flexible use of the message-passing facility by processes" is True. Blocking primitives in interprocess communication mean that a process is suspended until the necessary conditions for continuation are met.
This often relates to the availability of a message or the readiness of another process to receive a message. With blocking primitives, a process does not waste CPU cycles polling or checking for a condition to be satisfied. Instead, it is put to sleep and later awakened by the system when it can proceed, making this an efficient way to handle synchronization and communication between processes.
Moreover, the use of blocking primitives is flexible because it allows the design of communication protocols that can adapt to different computational needs and resource availabilities.
Blocking primitives refer to the programming constructs that allow processes to block and wait for messages in the message-passing facility.
These primitives enable efficient and flexible use of the message-passing mechanism by processes, as they can pause their execution until the required message arrives. For example, in languages such as Java, blocking primitives like 'wait' and 'notify' are used for inter-process communication.
