Answer:
Non blocking send.
Explanation:
Inter Process Communication (IPC) mechanism can be defined as a mechanism in which an operating system of a computing device allow processes to communicate with each other, as well as synchronizing their actions without using the same address space.
Basically, an Inter Process Communication (IPC) mechanisms enables the operating system to synchronize the actions of the processes and manage shared data.
This ultimately implies that, an Inter Process Communication (IPC) mechanisms makes multithreading possible on computer systems such as a program handling many user requests concurrently or at the same time. Additionally, Inter Process Communication (IPC) mechanisms performs at least two (2) operations; send message and receive message.
Inter Process Communication (IPC) mechanisms comprises of both blocking and non-blocking communication, it is called non blocking send if the sending process sends the message and resumes operation.
