Process-to-Process Delivery TCP UDP

Process-to-Process Delivery TCP UDP

PROCESS-TO-PROCESS DELIVERY – TCP UDP The TCP UDP transport layer is responsible for process-to-process delivery—the delivery of a packet, part of a message, from one process to another. Two processes communicate in a client/server relationship, as we will see later. The transport layer is responsible for process-to-process delivery. Types of data deliveries – TCP UDP Port […]
