In surfing through the internet and when the search engine directs you to a specific name site, is it really that simple? To Netizens just surfing for information and gets directed to sites with the most probable primary domain, it seems just typing and there you go. But it is not so simple for the webmasters or the web designers.

The domain name is part of an Active Directory setup in the network. The primary domain usually is www.example.com and is suppose to show your way to the particular website. Usually, these primary domain bring you to where you wish to go through "cookies". Well, it is a bit complicated to expound on how the "cookie" functions, but let's just describe it to be a set of data that is held by an intermediary to bring your computer browser to a specific site. And, primary domains are actually a set of these "cookies" in an organize manner. You see, it is so difficult to find a site if it were a set of numbers, and so the internet set it up to be of words interralated and specific that there aren't any domain that is the same. All are unique in words and extensions.

The primary domains that make the website, may be subdivided and are called sub-domains. Sub-domains are usually in http://sub.example.com/ formats. But why do we need sub-domains? Are they necessary? Sub-domains are actually just like folders within your root directory, wherein you can organize the index page to be products, games, or forms redirecting your visitors into specific links within your primary domain. Simply just links that brings your users to the specific information, but for webmasters and web designers, it is a lot more. Some use sub-domains to shield the confidential information and those that are for public access. On the other hand, some just wish to organize the data for quick restructuring or management like what we do with our file folders in our hard drives.

Not for the unfamiliar, the use of the sub-domain directory is delicate. A novice may make a mistake of over extending the sub-domains that it interferes with the identification by search engines and the formats of the "cookies". This may become so nasty that it destroys the way the browser reads the pointers, and you lose your traffic. The "cookie" impact should be studied well.

The simple search is so complex in the world of the internet, that the codes should be well spelled. We experience, as ordinary Netizens, the convenience in searching for our needed information, and it's not so common to us to really ponder on how the internet brings us to the sites we choose to go. Now, isn't it awesome that the internet have its own location system that keeps everyone on the right path always?
