What's the difference between Adaptive design vs Responsive design?

[Manishkumar12]

Responsive Web Design provides the optimal viewing experience of a website, no matter what type of device the user is seeing it on. Wikipedia describes it as “an approach aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from mobile phones to desktop computer monitors).”

Adaptive Web Design is different from Responsive Design in that there isn’t one layout that always changes. Instead, there are several distinct layouts for multiple screen sizes, and the layout used depends on the screen size used. For example, there could be a specific layout for mobile phones, tablets, and desktop computers – each of which are made in advance.
