It introduced features such as the System V init process and the System V IPC (Inter-Process Communication) mechanisms.
What are the advantages of sockets in Unix?
Sockets in Unix provide a powerful mechanism for inter-process communication (IPC) that facilitates both local and networked communication. They enable different processes, potentially on different machines, to exchange data seamlessly using standard protocols like TCP and UDP. Additionally, sockets support a variety of communication patterns, such as client-server and peer-to-peer, and are highly flexible, allowing for various data types and formats. Their integration with the Unix file system also allows for easy management and access control, enhancing security and efficiency.
