Scenario
Consider that there is a sales person named Mr. Zee in a Grocery store. He sends every day sales & profit reports on daily basis to Mr. A on e-mail ID “abc@yahoo.com”. Mr. A is the Manager in charge sitting in head office situated in other city.
The Network address of computer machine of Mr. Zee from where he generates the E-mail lies on the network with address 140.57. The e-mail server of the requested e-mail “abc@yahoo.com” is hosted at Network No.100.
For routing the data, there are number of Routers responsible for delivering the data based on IP addressing node to node. There is a router (R-1) attached to network 140.57 and Router (R-2) is the gateway router connected to the network No.100 where destination computer machine lies.
At the sender side the information will pass downward to the TCP/IP layered architecture and upward on receiver after being processed by different protocols on each layer.
