Alexa Traffic Rank - This is a ranking system set by alexa.com (a subsidiary of amazon.com)

Google rank web pages according to its popularity and importance based on inbound links and Alexa rank the websites according to its traffic, which is randomly sampled. That is the main reason of showing a different and contradicting statistics, specially, for a relatively small and new websites.

Alexa Rank is more important than page rank and basic thing is to improve Alexa Rank so that people trust you.

File extension .stm,STM file extension

A file with the .stm file extension is known as an Exchange streaming media file, a Scream Tracker 2 module or a SSI web page.

STM files store streamed native Internet content. New messages are saved to the STM file on the mail server until they are accessed by a user's mail client. When messages are accessed by a MAPI client, they are transferred to the EDB file and converted to the native Exchange format.
Web page that contains server side includes (SSI); references functions on the server that generates content for the Web page; processed by the server when accessed, which outputs HTML to client's Web browser.

Server Side Include Web pages may also use the .SHTM or .SHTML extensions.

Audio tracker module saved by Scream Tracker 2; contains tracks, patterns, and samples used for instruments that are played back in the songs.

Help how to open STM files:
Use any text editor or specialised application (Adobe Dreamweaver, Contribute). To open use web browser (Internet Explorer, Firefox, Opera)
stm file - HTML server side include file
When a video or email is sent as an attachment to an email address housed on a Microsoft Exchange server, the server saves the file as an exchange streaming media file. When you access your email, the server transfers the .stm file to its original file extension and then sends it to your email, where you can download it.

Nameserver,Domain Hosting,Web Hosting

Nameserver

Nameservers make it possible for visitors to access your website using a familiar domain name, instead of having to remember a series of numbers.

Nameservers on other networks can access information at the central registry up to 8 hours after registering .com and .net domain names and up to 48 hours for all other domain name extensions.

Domain Hosting and Web Hosting

There is a difference between "domain hosting" and "web hosting". Domain hosting refers to the nameservers that your domain name is directed to. The basic nameserver functions include email capabilities and website / browser resolution of the domain name. Web hosting refers to the web content of a web site.

In a common traditional setting, the nameservers of a web hosting company are used. However, web site content can still be published onto pages provided by a web hosting company and the domain name can be pointed or redirected to any specific page on the Internet or unique IP address.
