Process

Program in execution — includes code, data, stack, heap, PCB, open files. States: New→Ready→Running→Waiting→Terminated (+suspended).

IPC Models

  • Shared Memory: processes share region; fast, needs sync (mutex/semaphore) to avoid race. E.g., POSIX shm.
  • Message Passing: kernel-mediated send/receive via direct naming or mailbox/ports. No shared state, good for distributed, overhead due to syscalls. Indirect mailbox decouples.
    Contrast: Shared memory = speed but synchronization burden, tight coupling; Message passing = isolation, suitability for network, automatic sync but copy overhead. Modern hybrids use both.
