How about the following definitions?

- Initial layout viewport
 - The viewport which is given by the window or viewing area of UA
 - In general, the size of the viewport is the size of the window on 
the desktop browser, whereas that is as same as the physical pixels as
 depicted on the screen of the mobile device
- Actual(Used / Computed) layout viewport
 - The viewport which is applied cascaded viewport descriptors
 - The size of the viewport is as same as that of the initial 
containing block
 - Pixel dimensions are specified in CSS pixels.
- Visual viewport
 - The part of the page that is currently shown on the screen
 - Pixel dimensions are specified in hardware(device) pixels
