How do internet addresses work?

Today, if you want to go to a website, you often type a name and let your search engine or browser find it for you. Most people do not type out or consider the entire website address, also known as the uniform resource locator or URL. However, your success as a college student and critical thinker will rely on your understanding of how URLs work. We can look at the parts of a URL just as we could a sentence. Sentences have nouns, verbs, and objects. URLs have protocols, domain names, paths, and slugs.

Let's look at a sample URL from the Mapping Prejudice Project in Minnesota:

Mapping Prejudice

Broken down into its component parts it has:

https:// - hyper text transfer protocol secure, the scheme.
www - world wide web - called a subdomain, but often not used today
mappingprejudice - a domain name or host,
.org - the domain suffix.
resources - this is a path or directory
index.html - this is a slug

http vs https

http and https are called schemes, that is they are the accepted ways, or protocols, for how information is stored, requested, and received on the internet. There are other schemes, such as ftp, but http and https are the most common.
Hyper text is text that has other information attached to it with what we call links. Links allow you to access other resources by clicking a mouse or touching a pad.
Why are there two ways (https and https) for the internet to communicate? Consider this video:

✏️ Questions: Navigate to your college website: is it http or https? Is your favorite website for news http: or https:?

Domain names

Domain names use regular words to help us find internet addresses. Often the domain name will tell us what person, group, or institution is responsible for the website, but not always. For example, the University of Minnesota directs and hosts the Mapping Prejudice website. Note that we do not see the University of Minnesota domain (umn.edu) anywhere in the mappingprejudice.org URL . We need to read the "About" section of the site to learn it is associated with the University of Minnesota. To look up who owns a website see In Depth below.
Anytime you have problem with a website, check to see if its home domain name (sometimes called the root domain) is working. If the root domain name is working, then you can trouble shoot other aspects of the link.

<aside> ➡️ Did you know? Domain extensions — the .org, .edu, and .com endings of URLs — used to be useful for evaluating the credibility of websites: no longer. Websites can have any extension they want. Did you notice that domain extensions are largely meaningless when deciding if a website has credible information? We need to investigate the information on the site itself now. ****
