The relationship between clients and servers can be described using the analogy of dining in a restaurant. The client in this case is a restaurant patron, and the server is the kitchen. When you go into a restaurant you give your food order to your waiter (a client request). The waiter may be required to write down the order in a certain format so that the it can be read by the kitchen (analogous to the Hypertext Transfer Protocol set of rules governing the communication between client and server). Next, the kitchen takes the order (written in a particular format) and prepares the dishes in the order, much like a server returns an HTML file and any other files it links to (like CSS, JavaScript, or image files). When the order is ready, the kitchen sends it to the patron via the waiter, much like a server sends the files to the client.
