Both the Open Systems Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) networking models are important conceptual frameworks for understanding networks.
OSI Model explains networking concepts, and troubleshooting, While TCP/IP protocols suite are rules by which networks now operates.
OSI Vs. TCP/IP
Data Encapsulation
The term encapsulation refers to the process of putting headers (and sometimes trailers) around some data.
The five layer TCP/IP model, one step corresponds to the role of each layer.
Each term, however, refers to a different layer: segment for the transport layer, packet for the network layer, and frame for the link layer.
