OSI and TCP/IP Networking Models
In this training course you will be introduced to the OSI and TCP/IP networking models. This course will provide you with an understanding of both models, useful for learning, architecting, and/or operating large scale networks. To start with, we will review the Open System Interconnection model, which is a 7 layer reference model used to aid both learning, building, and troubleshooting of networks. Next, we will review the TCP/IP model, a more simplified 4 layer model that is used in the implementation of real world networks such as the Internet and/or private networks such as corporate LANs.
- [Instructor] Before we finish, let's do a quick review of what we've learned. We gained an understanding of the OSI model and each of its seven layers. We gained an understanding of TCP/IP model and detailed each of its four layers. We learned about the upper and lower layer groupings within each model. We learned briefly of the history of each model and the differences between the two models. We learned about how the TCP/IP model uses both logical and physical addressing schemes in the transmission of data. We provided an overview of how TCP/IP routes packets of data between devices. We reviewed the TCP/IP network stack in detail, discussing core protocols that it's composed of and summarized some of the common application protocols that leverage it. Finally, we spent some some time reviewing the TCP/IP network stack from top to bottom and how it's used to implement and operate real-world networks. Thank you for your participation, I do hope you've enjoyed this course on the OSI and TCP/IP networking models. Feel free to send any feedback and/or questions at firstname.lastname@example.org.
