What is a socket? Explain in detail how two processes communicate using

SOCK$\_$STREAM. Illustrate your explanations by a simple server$-$client program

that operates as follows:

$$ A client sends to the server a message including their name and an integer

number in the range $0$ to $999,$ e$.$g$.,$John $153..$ The name $($in this case

$$John$)$ is the first argument of the client program. The IP address of the

server is the second argument. The number is the third argument.

$$ The server first randomly generates an integer number in the range $0$ to $999$

and then waits for messages from clients.

$$ On receipt of a next message the server extracts the name of the client from

the message, compares the number sent in the message with the locally

generated number, and responds to the client with a message containing the

client$$s name, of the form $$Sorry John, you did not win.$$ if the numbers are

different, or $$Congratulations$,$ John! You are a lucky winner.$$ otherwise.

$$ The client receives the message from the server and prints it on the screen.
