Question

What does it mean by end to end communication??

Do routers do end to end communication??

Answer 1

Process to Process communication is called End to End communication.

Process is generally associated with a port number ( to distinguish between multiple process running on a system).

TCP is responsible for the delivery from the client system one particular process’s port to corresponding process’s port at server.

1. What do you understand by end to end communication?
2. Port number is assigned to a process in  a system. port to port (for each individual process) delivery is end to end communication.
3. do routers have processes? If ,no processes ;no port numbers. right and Routers are not responsible for end to end communication . if you recall Routers works only till network layer. right. again if you recall TL is responsible for end to end communication. I hope that answers your query.
