SNA (System Network Architecture)

System Network Architecture (SNA) is a framework developed by IBM to organize and manage network communication between computers and devices. It provides a structured way for different systems to connect, share data, and work together efficiently, even if they are different types or from different manufacturers. SNA defines protocols and procedures that ensure reliable, secure, and coordinated data exchange across a network. Think of it as a comprehensive communication blueprint that helps diverse systems talk seamlessly in large, enterprise environments.
