A Universal Resource Locator (URL), often called a web address, is what a web browsers uses to access resources stored on a web server. Think of it like a mailing address for a web page. The first part of a URL, called the hostname (e.g. ww.ubyssey.ca), is converted to an IP address (e.g. 220.127.116.11) through something called a DNS lookup, which tells the browser which server to send the request to. The server is then responsible for "routing" the remaining portion of the URL (e.g. /news/max-holmes-wins-vp-academic/), which is often the first task that a web backend must take care of.
