Every web server has a unique address so that other computers connected to the internet know where to find it on the vast network. The IP (Internet protocal) address looks something like this: 69.93.141.146.
HOW IT WORKS:
- Your web browser first needs to know which IP address the website "www.quackit.com" resolves to. If it doesn't already have this information stored in it's cache, it requests the information from one or more DNS servers (via the internet). The DNS server tells the browser which IP address the website is located at. Note that the IP address was assigned when the website was first created on the web server.
- Now that the web browser knows which IP address the website is located at, it can request the full URL from the web server.
- The web server responds by sending back the requested page. If the page doesn't exist (or another error occurs), it will send back the appropriate error message.
- Your web browser receives the page and renders it as required.
When referring to web browsers and web servers in this manner, we usually refer to them as a client (web browser) and a server (web server).
