Domain Name vs Fully Qualified Domain Name
When it comes to the world of websites and the internet, domain names are one of the most crucial components. They are what users type into their browsers to access a particular website. However, many people get confused between a domain name and a fully qualified domain name (FQDN). In this article, we will explore the differences between the two and why they are both important in the online world.
Domain Name
A domain name is essentially the address of a website on the internet. It is what users type into the address bar of their browsers to access a particular site. For example, in the domain name www.example.com, “example.com” is the domain name. Domain names are used to identify and distinguish websites from one another. They are unique to each website and are registered with domain registrars.
Fully Qualified Domain Name (FQDN)
A Fully Qualified Domain Name (FQDN) is a domain name that specifies the exact location of a particular resource on the internet. It includes not only the domain name but also the top-level domain (TLD) and subdomains. For example, in the FQDN www.blog.example.com, “blog” is the subdomain, “example” is the second-level domain, and “.com” is the TLD. FQDNs are used to provide the full hierarchical structure of a domain name.
Main Differences
The main difference between a domain name and a Fully Qualified Domain Name lies in their specificity. A domain name is more general and only includes the main domain identifier, while an FQDN provides a more detailed and precise location for a resource on the internet. Think of it like a street address – a domain name is the street name, while an FQDN is the full address including the house number and zip code.
Importance in Online World
Both domain names and Fully Qualified Domain Names are crucial in the online world for various reasons. Domain names are essential for creating a brand identity and establishing an online presence. They are what users will remember and associate with a particular website. On the other hand, FQDNs are necessary for technical purposes such as setting up servers, routing emails, and establishing secure connections.
Conclusion
In summary, a domain name is the main identifier for a website on the internet, while a Fully Qualified Domain Name provides the full hierarchical structure of a domain. Both are essential in their own ways and play different roles in the online world. Understanding the differences between the two can help website owners and developers better manage their online presence and technical operations.
