Responsive Websites Versus Smartphone Friendly Websites
The way responsive websites work is that depending on the dimensions of the browser, the design for the website adjusts itself and displays the information in an organised layout. It the website was not a responsive website, it would display only some portions of the actual website.
A smartphone friendly website, on the other hand, detects which device is trying to open the website and accordingly chooses the design layout to show for the website. So for example, if it detects that the website is being opened from a computer screen, it doesn’t change the layout and shows the website as is. If the website is opened from, say an iPhone, it detects that request and displays the design made for iPhone’s screen size and resolution.
