Encapsulation




1. The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above.

As an example, in Internet terminology, a packet would contain a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP), followed by the application protocol data.

2. The ability to provide users with a well-defined interface to a set of functions in a way which hides their internal workings.

In object-oriented programming, the technique of keeping together data structures and the methods (procedures) which act on them.
