      The area that is shared between two or more processes is called Shared Memory.This helps in the interprocess communication where you want to allow changes made in all the instances of a single application . Somethings seem HARD to do, until we know how to do them. ;-) _AnShUmAn_

        Normally each process has its own memory and data in processes A's memory can't be accessed in the memory of process B and vice versa. Shared memory is when the same physical memory is mapped into multiple processes. In our example this means that process A and B share some memory and thus the data in it is shared. Normally only a small amount of memory will be shared. Steve

          Hi Prashanth V, Hw are u ?? Shared Memory is an efficeint means of passing data between programs. One program will create a memory portion which other processes (if permitted) can access.
