What is a URL and How Does It Work

Every time you log into your web browser to read some news, do shopping, or browse the internet, you will definitely deal with a web address. This address is meant to lead browsers straight to their destination point all over the web. It is always useful to know what is a URL in order to make your internet surfing easier and safer.

What Is a URL?

URL is an abbreviation for Uniform Resource Locator. To put it simply, it means the full address, which is used by the web browser in order to reach a certain webpage, image, video, or file on the Internet.

It is important to mention the fact that despite the tendency of most people to confuse the notions of “domain name” and “URL”, there is one thing that must be considered: these two notions are not quite the same. 

Components of a URL

The standard URL includes several different components, which help in forming it:

• Protocol (scheme): The initial part, which determines the way the data will be transferred (https://).
• Subdomain: The optional prefix, placed before the domain (www or blog) and helping to structure some parts of the website.
• Domain name: The name of the website itself (networksolutions.com).
• Path: The specific location of the page within the server (for example, /blog/what-is-a-url).
• Parameters & anchors: The optional parts, which can be added to the URL to filter certain information and jump to a certain header on the page (? or #).

How Does a URL Work?

The process of URL resolving is performed within seconds after inputting the link in the browser and includes several steps:

• Address Analysis: Address analysis refers to analysis of the protocol, domain, and path that was provided by the user in the browser’s address field.
• DNS resolution: As computers cannot use any symbols other than numbers to communicate with each other, DNS resolves the domain name into the IP address.
• Connecting to the server: The browser connects to the web server by using the obtained IP address and asks for the needed path.
• Data Reception: The server returns the required data packets, and the browser uses them to show the webpage.

Conclusion

Browsing on the internet requires an understanding of the addressing system of the digital world. Understanding what is a url and how its components interact with each other makes this process much easier. 

It does not matter whether you are developing a website for your business or surfing the internet; knowing how web addresses work will help you browse the internet more safely and efficiently.
