Read MoreDifferentiate between shared memory and message passing model in OS.
Shared memory system is a fundamental model of inter-process communication where cooperating processes communicate by establishing a shared memory region within their address space. This approach allows multiple processes to access the same physical memory location for data exchange. The shared memory concept works on the principle of fastest inter-process communication. When a process wants to initiate communication and has data to share, it establishes a shared memory region in its address space. Another process that wants to communicate must attach itself to the initiating process's shared address space to read the shared data. Message Passing Model ...
