Students will be expected to not only define, but also discuss the characteristics of URL and URI. Students will also be expected to describe the purpose of a URL.
Characteristics of a URL[edit]
A Uniform Resource Locator (URL), is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI).[2]
