Study Notes
- TCP/IP protocol suite is also known as the Internet protocol suite and is compared with the OSI model in the video.
- OSI model consists of 7 layers: physical, data link, network, transport, session, presentation, and application, while TCP/IP can have either a 4-layer or 5-layer architecture.
- The difference between the 4-layer and 5-layer architecture lies in how the physical layer and data link layer are structured.
- TCP/IP model is more practical and implementable compared to the theoretical nature of the OSI model.
- TCP/IP was developed by ARPANET and funded by DARPA, emphasizing practical use over theoretical documentation.
- The TCP/IP model includes layers such as the application layer, transport layer (utilizing TCP and UDP), internet layer (with IPv4 and IPv6), and network access layer.
- TCP/IP model supports client-server architecture (centralized authority) and peer-to-peer architecture (decentralized, mutual connections) for data transfer.
