What is the internet?

How are computers linked via the internet?

The journey of data sent between two devices

How do we surf the web?

  • http: short for Hyper Text Transfer Protocol which is a set of rules for fetching resources (HTML, CSS, images etc.)
  • www: the sub-domain
  • facebook: the domain name
  • com: the top-level-domain

Note:

1. The browser checks the cache for the DNS record

2. The browser sends an HTTP request to the website’s server to fetch resources
