I have read and learnt the fundamentals about the OSI model and its layers but just wondering is there a difference between the OSI model and IP networking or is it covered by OSI model?

Bit confused with the terminology than anything.

Also my final question actual software say a browser like chrome, is that considered part of the application layer in the OSI model or are the HTTP and other functions served by the layer only included. I am going with the latter option hence the word 'served'. Just want to know in case I get asked in a test to draw some sort of diagram...


In addition to the OSI model, there is the Internet protocol suite model. The OSI model would place IP networking at layer 3, the network layer.

A web browser is going to have components of the transport layer and all layer above it as they include TCP/port numbers functionality, http session, encryption, ECMA/Javascripting, etc.
