First, get the code from the zip file working on your machine. If you can, work with someone else $($or with two machines$)$ and see if you can get the

client to run on one box and communicate with the server on another. In your PDF$,$ assume that you have deployed the client and server to two

separate nodes $($machines$).$

Use diagrams to communicate the three kinds of structures involved in your client$/$server system that tells knock$-$knock jokes.

Create a diagram for each of the three structure types in the definition of software architecture $($see figures $1\mathrm{.}2-1\mathrm{.}10).$

You can use any tool that supports UML, like lucidchart, Visio,

draw.io$,$ etc.
