I am novice in graphics programming, so correct me if I am wrong.

0) In SVGA, we do bank switching because the entire screen
   is divided into different banks?
1) Each bank starts from A000?
2) do EGA/VGA use bank switching?
3) When I look at some posted message, I got words like '4K windows',
   are they referring banks?
4) how do you know what pixel is addressed in what bank?
   (how do we know which bank should we use when a specific
    location of pixel is given, says (100,100))

thanks, guys
