The process for requesting and receiving a web page (Wijesinge, 2017):
1. The URL is sent to a DNS (Domain Name Server) that provides the IP address of the site. The caches are checked first.
2. Browser opens TCP connection with the web server.
3. The server receives a HTTP GET request, serves back the requested resources and sends a HTTP response.
