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.

Protocol

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.

Sub domain

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.

Domain Name

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

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.

Path

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.

Query

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.

Parameter

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 (&).

Fragment

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

Fully Qualified

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.

Relative

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’.
