A Tour of the Internet and Networking

The Internet is really a network of networks. That is, the Internet is an interconnected set of privately and publicly owned and managed networks. Any network connected to the Internet must run the IP protocol and conform to certain naming and addressing conventions

The Application Layer

The application layer is confined to end systems. Core devices such as switches and routers don't understand anything about application and are confined to the 3 bottom layers of our 5-layer Internet stack!

The Transport Layer

Transport layer is responsible for transmitting data between different processes in the layered network architecture. You will learn about the principles of transport and how these are implemented in actual protocols (specifically UDP and TCP).

The Network Layer

The process-to-process communication in the transport layer depends on services provided by the layer under it, the network layer which is responsible for host-to-host communication. This is probably the most important and interesting layer in the networking stack. While the application and transport layers are implemented only in the end systems, the network layer is implemented across the whole network, so every router in the network has to process it.

In computer networking, the link layer is the lowest layer in the Internet protocol suite, the networking architecture of the Internet. The link layer is the group of methods and communications protocols confined to the link that a host is physically connected to.
