In Simple way i can tell you something about Networking If one is thorugh enough in OSI layer concept the whole Networking lies on OSI layer concept which contains 7 layers on Source Side and 7 Layers on Destination Side.OSI stands for Open Systems InterNetworking.The 7 layers in OSI layer concept are as below :

1)Presentation Layer
2)DataLink Layer
3)Network Layer
4)Transport Layer
5)Session Layer
6)Physical Layer
7)Application Layer.

If you are through in all these 7 Layers then you can say you know Networking concept.Each and Every Layer provides you a brief description of Layer how it works and how it is presented in real time scenario.


I think before learning computer networking you have to learn about networking devices like router, bridges, network racks and how to use this devices & how to do basic cabling, once you will get the knowledge about networking devices & uses you can easily learn computer networking.
