I know that in Internet Protocol Stack there are actually three layer. They are Application, Internet and Transport. Let's say HTTP in Application layer will be converted to TCP in Transport layer and TCP will be converted to IP in Internet layer.
But practically when I tried to capture a network traffic from internet, I can only understand the HTTP layer and I can't understand what is in TCP and IP.
I am using wireshark for capturing network traffic.
Please explain the process or provide a simple example for this.
