Question

With the aid of diagram, describe the connection-oriented socket process between server and client.

b) Explain what are the difference between stream socket and datagram socket? Give an
example for each of them.?

Answer 1

A. Diagram for the socket process between server and client is the following:

Explanation:

On the server side, there is a socket creation at first. SetSockopt helps in manipulating options for the socket. This is completely optional, but it helps to reuse address and port. It also prevents error related to addresses. Bind binds the socket to the address and port number specified in address function. When Client tries to connect to the socket, the server listens to the request and accept it. Hence, there is a communication created between client and server.

B. Difference between Stream Socket and Datagram Socket:

Stream Socket	Datagram Socket
Dedicated and end-to-end channel between server and the client.	No dedicated and end-to-end channel between server and client.
Use TCP protocol for data transmission.	Use UDP for data transmission.
Data sent/received in similar order.	Data sent/received order might not be the same.
Reliable and lossless.	Not reliable and also may lose data.
Example: A phone call where one side places a call and other receives it. They can now exchange information.	Example: A message sent from one side, it may not reach its destination.
