Which layer is responsible for process to process delivery in a general network model?
Answer:
In a general network model, the layer responsible for process-to-process delivery is the Transport Layer. The Transport Layer ensures the reliable and accurate delivery of data by establishing, maintaining, and terminating connections. It provides end-to-end communication between the source and destination processes on different hosts. This layer is crucial for error recovery, flow control, and data segmentation. The most common transport layer protocol is the Transmission Control Protocol (TCP), known for its reliable, connection-oriented communication. Another protocol at this layer is the User Datagram Protocol (UDP), which is connectionless and provides faster but unreliable communication.
