What is the Difference Between Root Domain & Subdomain
Hi, Lads today we will compare Root and sub domain with each other and see whats the main difference between them..
Starting with Root domain ..
A site’s root domain is the highest level in the Internet domain structure. Technically, the root domain itself is nameless and contains the top level domain — or domain extension — such as .com, .org or .net. The root domain also contains the second level domain, or the readable part of the address, such as “Microsoft” in http://www.Microsoft.com. The third level domain refers to the host server, and precedes the other two parts. “WWW” is the most common third level domain, but some root domains may contain additional servers, listed as “WWW2” or other names. Many people use the term “root domain” to refer to that domain’s entire contents, even though this is not strictly correct. The correct term for this collection of domain parts is the Internet domain name.
A subdomain is a lower level component of a domain name, often for a separate part of the site. Microsoft’s main website has a separate subdomain at support.Microsoft.com for help topics, downloads and other support activities. Using a subdomain allows the company to separate all its support information into one place, where it’s easier to find. Separating part of the site into its own subdomain also makes it easier to track which users come to the site for support activities. Subdomains also work well when the domain owner wants to create more than one site without buying a new domain — for instance, a business webpage and a personal site.
Some companies use subdomains to make it easier for visitors to reach their sites. Microsoft.com and http://www.Microsoft.com are not obviously different domains, but they do look different in the domain structure. Search engines sometimes categorize two versions of the same page on the main domain and subdomain as different pages, changing page ranks accordingly. Site owners can fix this problem by adding code to redirect from the subdomain to the main domain seamlessly. Users don’t notice the difference between the two domain types, and search engines won’t assume the site uses duplicate content.
Subdomains Versus Subdirectories
It’s easy to confuse subdomains with subdirectories, since they look similar in the website’s directory tree. However, a subdirectory has a different address; it uses the format http://www.Microsoft.com/en-us. Subdirectories work well to create a different category for content that is still closely related to the main site. This keeps files and pages organized. In the above example, Microsoft uses the en-us subdirectory to hold files for its English site targeted to the United States.
