What Does PDU Stand For?

PDU stands for Protocol Data Unit

A Protocol Data Unit (PDU) is a fundamental unit of data that is transmitted across a network. It encapsulates data specific to a particular protocol at a certain layer of the OSI (Open Systems Interconnection) model, including necessary headers and trailers used for communication between devices. Each layer of the OSI model employs its own PDU format, such as packets at the network layer and frames at the data link layer, facilitating organized and efficient data exchange.
