Final answer:
The most desirable order of execution of the four key primitive operations for IPC (interprocess communication) is connect(), send(), receive(), and disconnect().
Step-by-step explanation:
The most desirable order of execution of the four key primitive operations for IPC (interprocess communication) depends on the specific requirement of the communication process. However, a common order of execution is:
- connect(): This operation establishes a connection between two processes or systems.
- send(): This operation is used to send data or messages from one process to another.
- receive(): This operation is used to receive data or messages from another process.
- disconnect(): This operation terminates the connection between two processes or systems.
It is important to note that other orders of execution may also be appropriate depending on the specific communication requirements.
