URL Full Form: Here in this article, we will be sharing information about the URL. We have provided in-depth information about the URL and its parts that are also important to understand if you are reading about URL. So let us begin.
URL is an abbreviated form for Uniform Resource Locator or URL full form can also be mentioned as Universal Resource Locator.
Uniform Resource Locator refers is a kind of web address. It specifies the location of the particulars on a computer network. It specifies the address of a resource on the Internet and this particular resource can be a webpage or any file.
URL is like an address of the resource just similar to the residential address of a particular person in a particular street. This is the reason it is denoted as Web Address also.
It was created back in the year 1994 by Tim Berners-Lee who was the inventor of the World Wide Web (www).
Every URL contains following information:
* Protocol or the scheme name
* A domain name
* The full path of the resource
PARTS OF URL
URL consists of certain elements and then forms a complete address of a specific resource. Let us see what are the different parts that form a complete URL address.
The protocol in a URL defines the route of the communication between a web browser and a web server while sending or receiving a web page or document over the Internet.
HTTP is the most common protocol that stands for Hypertext Transfer Protocol. It lays the foundation for data transfer over WWW.
Other than HTTP, there are FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and more.
The sub division of the main domain name is called a subdomain. We will next discuss Domain’s name that will give you more clarity about this.
A domain name is the unique identification of a website on the World Wide Web or as we say the Internet. When you search for a particular website, let’s say WikiGranth which is the name of this blog. The domain name would look like this: www.wikigranth.com
A name registered with the DNS (Domain Name System) is a domain name.
Port number is an important part of URL but it is rarely visible there. It is always separated by a colon when declared in the URL. In case it is not declared a standard is defined about the port that port 80 is used in HTTP and port 443 is used in https.
A path is a file or directory in the webserver. It is similar to the path or roads we take to reach a particular address in a city. The same concept implies the path of the URL.
A query is denoted as a question mark (?) followed by one or two parameters. It is usually found in the URL of dynamic pages. Dynamic pages are the one that is generated from a specific database of user content.
They are seen in the query of a URL as mentioned above. Parameters are the bits of information that is entered by a user who is looking for specific content on the internet. The two parameters are separated by the ampersand mark (&).
The page reference inside a domain is called a fragment. It is presided by a (#) and appears at the end of the URL. It is a subsection on a web page only.
Types of URL
There are essentially 3 types of URL available
This type of URL is used to target a specific file on the Internet without fail. It is mainly used on any specific page, any particular website, any prominent email, from any computer. It always opens the same address.
For example, surfing the Amazon shopping website from your computer or tab will show you the same home page.
From the Root
These URLs are like short cuts. They simply eliminate HTTP and domain names. They work on any page that resides in the same domain name. These URLs begin with a slash (/) that is the replacement of the main domain name.
These URLs are easy to write. But there exists one problem that they only work for the page that they exist on. The same code if used on another page then the relative URLs will not work.
URL and IP address
Usually, people think that URL and IP address are similar in meaning. But this is not the case even though they are used interchangeably.
A URL contains a specific location, a protocol, and a resource of the web page. Whereas an IP address only specifies the location.
A URL always requires a Domain Name System to operate while it is not the case with an IP address.
How to enter URL
A URL can be entered manually by typing it in the address bar of your web browser. If the particular URL does not contain a server then the browser will display ‘Server Not Found’ and if the URL is not entered correctly then the browser will show ‘Error 404’. We tried to imbibe all the important points related to the URL in this article. We hope this was helpful and was able to solve your queries regarding the URL.
