Ipc memory

In computer software, shared memory is either • a method of inter-process communication (IPC), i.e. a way of exchanging data between programs running at the same time. One process will create an area in RAM which other processes can access; • a method of conserving memory space by directing accesses to what would ordinarily be copies of a piece of data to a single instance instead, by using virtual memory mappings … In computer software, shared memory is either • a method of inter-process communication (IPC), i.e. a way of exchanging data between programs running at the same time.
