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
