This module introduces us to the field of web development and teaches us the basic nuts and bolts.

Zero to Hero in Front-end Web Development

If you are new to web development, this module is designed to provide a structured approach to learning the basics of web development. It will provide the foundational knowledge required to learn web development and understand the different technologies available in this field. Moreover, it comprehensively covers the foundations of web development, from the basics of networks to the principles of front-end web development with HTML, CSS, and JavaScript.

After completing this module, you will have a solid foundation in web development and be comfortable learning any web technology.

Web Development: A Primer

So far, we have covered all the basics of how web applications deliver data to an end-user through a network. Starting from the initiation of a TCP connection on the transport layer, all the way to the resolution of IP addresses through DNS servers; we have outlined the communication process between clients and servers. To make things clearer, we will now look at exactly how any given data packet travels through the web to reach its destination. 

## Packets through the Internet
This video gives a nice introduction to how packets travel through the Internet. This video is a bit dated, and some terminology used in it might not exactly be up-to-date, but the underpinnings are essentially the same today. It is a nice overview for beginners.
