Can someone please thoroughly explain what a URI is?

    • I am not sure about the context but URI generally refers to Uniform Resource Identifier. See Wikipedia for more:

    In information technology, a Uniform Resource Identifier (URI) is a string of characters used to identify a resource. Such identification enables interaction with representations of the resource over a network, typically the World Wide Web, using specific protocols. Schemes specifying a concrete syntax and associated protocols define each URI. The most common form of URI is the Uniform Resource Locator (URL), frequently referred to informally as a web address. More rarely seen in usage is the Uniform Resource Name (URN), which was designed to complement URLs by providing a mechanism for the identification of resources in particular namespaces.

    URL是标识资源的URI，也提供了通过描述访问资源的方式来定位资源的方法。URL是URI URI不一定是URL
