Question

(prima/prima) What are the functions of sockets in networked applications? Explain your answer with a case scenario where you are receiving 10 packets from a node. How will the socket perform its role?

PLEASE write your answer in your own words! thanks

Answer 1

Sockets are used for server and client interactions. It is an endpoint of two way communication link .

A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number. Every TCP connection can be uniquely identified by its two endpoints. That way you can have multiple connections between your host and the server.

A packet is a part of the larger data . When there are 10 packets at a node the packets will be send one by one to the client . The socket will first establish a connection between the client and server . once the connection is established the packets are send to the required port number.
