Describes what is layering and the different layering models used in computer networking
Computer networks theory of operation has lot of similarities with postal networks. This post briefly describes the similarities between a postal network and a computer network with respect to layering. The Hybrid 5-layer model is considered for comparison purposes.
This post briefly discusses about the layers that are processed at the end nodes (sending and receiving computers) and at the intermediate nodes (Layer1 Hubs/repeaters, Layer2 switches, Layer3 Routers) when a data unit (packet) is transferred between the end nodes.
Describes the process of encapsulation and decapsulation in computer networks and the need for them.
Gives an overview of the TCP/IP layering model and briefly describes the role of each layer
Describes the seven layer OSI model used for computer communication and gives a brief overview of the functionality of each layer.
Describes the meaning of the term communication protocol and gives examples
