Introduction
A Uniform Resource Identifier (URI) is an address that uniquely identifies a resource on the Internet. It is used to locate web pages, images, videos, and other types of files on the World Wide Web. URIs are similar to URLs and URNs, but they have distinct differences. The purpose of this article is to provide an overview of what a URI is, and explain the basics of how it works.
What is a Uniform Resource Identifier (URI)?
A Uniform Resource Identifier (URI) is an address that uniquely identifies a resource on the Internet. It is used to locate web pages, images, videos, and other types of files on the World Wide Web. URIs are similar to URLs and URNs, but they have distinct differences. A URL (Uniform Resource Locator) is used to locate and access a particular web page or file on the Internet, while a URN (Uniform Resource Name) is used to identify a resource without specifying its location. A URI combines both of these concepts, and can be used to both identify and locate a resource on the Internet.
The benefits of using URIs include: they are easy to remember; they are universal across the Internet; they are more portable than URLs; and they are more secure than URLs. Additionally, URIs can be used to refer to resources outside of the web, such as email addresses, phone numbers, and physical locations.
The Basics of Uniform Resource Identifiers (URIs)
A URI consists of three parts: the scheme, the authority, and the path. The scheme indicates the type of resource being accessed (e.g., http for webpages, ftp for files). The authority is the domain or hostname of the server where the resource is located. Finally, the path is the actual address of the resource. For example, in the URI http://www.example.com/index.html, the scheme is http, the authority is www.example.com, and the path is /index.html.
There are several different types of URIs, including relative URIs, absolute URIs, and fragment URIs. Relative URIs are used to refer to resources within the same domain, while absolute URIs are used to refer to resources located on other domains. Fragment URIs are used to refer to specific sections of a web page.
Understanding Uniform Resource Identifiers (URIs): A Guide
In order to create and use URIs, you need to understand the elements of a URI. The most important element is the scheme, which indicates the type of resource being accessed. Common schemes include http, https, ftp, mailto, and tel. The authority is the domain or hostname of the server where the resource is located. The path is the actual address of the resource. Finally, the fragment is used to refer to specific sections of a web page.
Once you understand the elements of a URI, you can create your own URIs. To do this, simply combine the scheme, authority, and path into one string. For example, the URI http://www.example.com/index.html could be created by combining the scheme http, the authority www.example.com, and the path /index.html.
Once you have created a URI, you can use it to access a resource on the Internet. Simply enter the URI into your browser’s address bar and press enter. The browser will then attempt to locate and access the requested resource. If the resource is found, it will be displayed in the browser window.
