What is the URL (Uniform Resource Locator)?

A uniform resource locator is the address of a resource on the internet or the World Wide Web. It is also known as a web address or uniform resource identifier (URI). For example, https: www.Google.com, which is the URL or web address for the javatpoint website. A URL represents the address of a resource, including the protocol used to access it.


What is the URL

A URL includes the following information:

  • It uses the protocol to access the resource.
  • It defines the location of a server by IP address or the domain name.
  • It includes a fragment identifier, which is optional.
  • It contains the location of the resource in the directory of the server.

A URL forwards user to a particular online resource, such as a video, webpage, or other resources. For example, when you search information on Google, the search results display the URL of the relevant resources in response to your search query. The title which appears in the search results is a hyperlink of the URL of the webpage. It is a Uniform Resource Identifier, which refers to all kinds of names and addresses of the resources on the webservers. URL's first part is known as a protocol identifier, and it specifies the protocol to use, and the second part, which is known as a resource name, represents the IP address or the domain name of a resource. Both parts are differentiated by a colon and two forward slashes like https: www.Google.com

http:// or https://

The http is a protocol that stands for Hypertext Transfer Protocol. It tells the browser to which protocol will be preferred to use for accessing the information that is specified in the domain.

The https (Hypertext Transfer Protocol Secure) is an enhanced protocol as compared to http as it concerned with security. It provides the surety that the information, which is transmitted over HTTP is secure and encrypted. The colon (:) and two forward slashes (//) are used to separate the protocol from the rest of the part of the URL.

www.

The www is used to distinguish the content, which stands for World Wide Web. This portion of the URL can be left out many times, as it is not required. For instance, if you type "http://javatpoint.com," you will still get the javatpoint website. For an important subpage, this portion can also be substituted, which is known as a subdomain.

Google.com

The javatpoint.com is the domain name for the website, and the .com is called TLD or suffix. It helps to identify the location or type of the website. For example, ".org" stands for an organization, ".co.uk" stands for the United Kingdom, and ".com" is for commercial. There are various types of domain suffixes available; you are required to register the name through a domain registrar to get a domain.

jtp.htm

The jtp.htm is the name of the web page, and the .htm is the file extension of the web page, which describes the file is an HTML file. There are many other file extensions available on the internet such as .php, .html, .xml, .jpg, .gif, .asp, .cgi, etc.

Where is the URL located?

A URL is located in the address bar or search bar at the top of the browser window. The URL is always visible in the desktop computers and laptop unless your browser is being displayed in full screen. In most of the smartphones and tablets, when you scroll down the page, the URL will disappear and only show the domain when visible. To visible the address bar, you need to scroll up the page. And, if only the domain is shown and you want to see full address, tapping on the address bar to show the full address.

What characters cannot be used in the URL?

It is realized by many people that space is not allowed in a URL. The URL string can contain only symbols ! $-_+*'(), including alphanumeric characters as it is documented in RFC 1738. Any other characters must be encoded in the URL if needed.

Is an IP address the same as a web address or a URL?

An IP address is not the same as a web address or a URL, as it is a unique number that is assigned to each device on a network. A domain name is assigned a unique IP address on the World Wide Web, and when entered an URL like javatpoint.com, it is translated by DNS into an IP address that used by routers to find web servers. Instead of using an IP address, a domain name is used as it is easy to remember by humans. For example, to remember an IP address like 216.58.216.164 is hard, and much easier to remember 'javatpoint.com.'
