The OSI Model is an essential learning tool for understanding networking principles, but it is not widely used in real-world implementations. Instead, the simpler TCP/IP model dominates modern networks. Despite its theoretical nature, the OSI model remains crucial for network engineers, aiding in troubleshooting, protocol development, and security implementation.

The course was pretty good, got a good knowledge of Open System Interconnect (OSI) Reference model in detail. Got to know about how each layer works in coordination with the others.
