Computer Networking

PDU stands for Protocol Data Unit, which is a term used in networking and telecommunications to refer to a unit of data that is transmitted over a network. The PDU is used to describe the format and structure of data at different layers of the OSI model, which is a conceptual framework used to standardize communication protocols.

Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies.

In networking, a protocol data unit (PDU) is the basic unit of exchange between entities that communicate using a specified networking protocol.
