At one point in time they were competing versions of Unix. System V was owned by Bell Labs (the so-called "real" Unix), and the BSD version was a somewhat friendlier version put out by the folks at the University of California - Berkeley.
The shell environments were different as well, with the BSD version standarizing on the C shell (csh) and the System V version using either the Korn or the Bourne shells (ksh or sh).
Most of the commands were the same, as was the "C" compiler (from the user's standpoint).
Environments that were written for one version could be run in the other with little or no modification.
There were also some minor differences in the C system calls and the runtime libraries.

What are the different BSD and SVR4 communication mechanisms?
BSD (Berkeley Software Distribution) and SVR4 (System V Release 4) utilize different communication mechanisms for inter-process communication (IPC). BSD primarily employs sockets, which facilitate network communication, as well as pipes and shared memory for local IPC. In contrast, SVR4 includes System V IPC mechanisms such as message queues, semaphores, and shared memory segments, providing a more comprehensive set of tools for process synchronization and communication. Both systems support Unix domain sockets, but their approaches to IPC reflect their respective design philosophies and use cases.
