Write an analogy to describe the relationship between clients and servers. The client and server relationship is like ordering products from Amazon. The customer (client) creates an order for a product from Amazon (server). The server receives the request and ensures that the person is able to purchase it. If they are able to purchase it, Amazon (server) sends by the requested product or products (resources) back to the client.
Draw a diagram of the request/response cycle. You can draw your diagram by hand and take a photo to add to your Gist.
