Now that we have a basic idea of socket APIs and the structure of networked programs, we are ready to begin our first program. By building an actual real-world program, we will learn the useful details of how socket programming actually works.
As an example task, we are going to build a web server that tells you what time it is right now. This could be a useful resource for anybody with a smartphone or web browser that needs to know what time it is right now. They can simply navigate to our web page and find out. This is a good first example because it does something useful but still trivial enough that it won't distract from what we are trying to learn—network programming.
