Explain the concept of encapsulation in the context of the OSI Model.

Encapsulation in the context of the OSI Model refers to the process of adding protocol-specific headers and trailers to the data as it moves down the layers of the model. Each layer adds its own header and trailer to the data received from the layer above it, creating a new encapsulated unit known as a protocol data unit (PDU). This encapsulation allows for the data to be properly formatted and understood by the receiving layer at the destination. Additionally, encapsulation provides a way to separate the responsibilities and functions of each layer, enabling modular design and interoperability between different network devices and protocols.
