Answer:
Extreme programming is a software development technique which is used to enhance software quality and it's response to ever changing customer requirements.
Testing
Testing is main focus in extreme programming.Extreme programming addresses testing in a way that if a minute testing can eliminate a bit of flaws, extensive testing can terminate a lot of flaws.
Evolution in Extreme programming is like this:-
Coding:-First programmers will code the problem.
Testing :- Testing is done to remove flaws.
Listening:- Programmers must listen to the customers to what they need.

Answer: Networking protocols are important as they define a set of rules to be used for exchanging information between computer nodes.
Explanation:
in terms of networking it is required for the source and the destination to have a set of predefined rules which enables the router to send and receive information across the network in such as way that both the ends are able to receive the messages.
The information exchange takes place first by the client by introducing itself to the remote server. the remote server upon receiving the information uses some form of handshaking and acknowledges the client of the receipt of the message.
besides this there are many routing protocols which tells us about the way how packets are sent from the client to the source. There are two types of routing protocols:
1. static routing protocols
2. dynamic routing protocols.
