FQDN (Fully Qualified Domain Name) is the full address of a specific device or resource on the Internet that consists of a host name and a domain name to guarantee unique identification and correct data communication between different locations on the network.
FQDN stands for Fully Qualified Domain Name, and it is a term used in the internet and networking world. An FQDN represents a complete and unique address of a specific resource or device on the Internet.
An FQDN consists of two main parts: hostname and domain name. The host name is the name of the specific computer, server, or device where the resource resides, while the domain name identifies the organization or group that owns the domain. These parts are usually separated using periods.
For example, we can take the FQDN: www.example.com. Here is "www" the host name for the web server containing the resources, while "example.com" indicates that the domain is owned by the Example company.
This system is used to give each device on the Internet a unique identification so that communication between them can take place correctly. By using the FQDN, you can avoid misunderstandings because it provides precise information about where you want to send data or retrieve resources from.
