A domain name is basically a Web site address. For example, “learningglue.com” is the address of the Learning Glue Web site; it’s also the site’s domain name.

A URL is a Uniform Resource Locator and consists of the following components:

• scheme://domain

A scheme refers to the protocol used to access a resource on the Internet, typically this will be either http or https. So the Learning Glue URL is:

• https://learningglue.com

For completeness, a domain includes a domain name extension that is called a “top-level domain (TLD).” These are divided into three different categories called gTLD, ccTLD and the lesser known iTLD. Some example of each are:

generic top-level domains (gTLD)	country code top-level domains (ccTLD)	infrastructure top-level domains
.com	.ie	.arpa
.net	.co.uk
