Layer 5 (Session)

Layer 5, known as the Session Layer in networking, is responsible for establishing, managing, and terminating connections between applications. Think of it like a conversation between two people: it sets up the meeting time, keeps the dialogue going smoothly, and decides when to end the chat. This layer ensures that data from one application is properly linked to the right application on another device, maintaining the flow of information without interruptions. It handles things like session checkpoints and recovery, so if there’s a hiccup, the conversation can resume without losing context.
