1. The client and server relationship is considered to be the backbone of the web. In fact, without computers or programs to
act as clients and other computers or programs to act as servers, you could not have the web. Understanding how clients and
servers communicate is imperative for understanding how the web works. To keep it simple, clients are the front-end devices
or programs (such as a web browser) that enable users to access services and/or software that is served to the client, over
the internet, by servers.
