Networking model
A networking model is an abstract framework that organizes the functions and layers involved in communicating data between network endpoints.

A networking model is a framework that organizes the functions required for data to travel from a source to a destination over a network.
- How it is used
- Organizes network functions into layers so protocols and communication behavior can be understood systematically.
- How deep it goes
- Defines OSI and TCP/IP layers and their broad roles, while deferring the exact mechanisms of network communication.
- Examples
- Uses email delivery across Ethernet or Wi-Fi and contrasts hop-to-hop MAC addressing with stable destination IP addressing.
- What you can do after
- Evaluate how protocols and addressing contribute to moving data between applications, hosts, and network hops.

A networking model is an abstract framework that describes how messages are communicated between senders and receivers across a network.
- How it is used
- Explains how clients, backend services, and infrastructure communicate across a network.
- How deep it goes
- Defines message communication and outlines four TCP/IP layers, while stopping short of detailed layer-by-layer implementation.
- Examples
- Uses browser-to-backend and backend-to-database communication as concrete examples, supported by a TCP/IP layer diagram.
- What you can do after
- Evaluate how internet messages move between client and server processes using the TCP/IP layer structure.
