websites for mobile (abbreviation of mobile > m )

[Kaitlyn]

That means you're on the Mobile site meaning your on your phone or tablet

[John Smith]

It is the "mobile device" version of the web page you are looking at. Most professionally made web pages have a "PC" version for computers and a "mobile" version for smartphones and tablets, since the screens are much smaller.

The web server detects what type of device the data request comes from and returns the page appropriate to the device you are using.
