SHM:it's an area of storage that can be read and written by more than one process.MSGQ:A message queue is like a pipe,by using more comprehensive mechanism we can read message from both end.SHM:It provides no inherent synchronizationMSGQ:It provides inherent synchronization,So the writer can never fail after writing only a partial message, and the reader will either retrieve a complete message or nothing at all.SHM:possiblity of occuring race condition.MSGQ: No race conditon actually occure.SHM: fasterMSGQ:slower than shared memory
