CS-69 : TCP/IP Programming of June 2001

Quesetion Paper of CS-69: TCP/IP Programming Ql(i) Design client/server algorithm using the UDP protocol. The algorithm should have UDP client and UDP server. The client should prompt a user to type a line of text, send it to the server and print it out. The server should simply act as a simple echo server. After responding to the client, the server closes the connection and then waits for the next new connection. (ii) Identify the address class of the following IP address.
