Could someone describe CUI (Character-based User Interface) in a brief way?

CUI is pretty much a grid of characters which creates a user interface on the screen. It's also possible to create custom characters to create actual graphics for something like a game instead of just having text.
Different systems handle this differently depending on how much memory they have, more memory allows for more complex characters, higher color space and a higher resolution grid. For example a Commadore 64 with 64KB of memory will be very limited when compared to a newer MS-DOS system with 64mb of ram. (Not an amazing example, but you get the idea...)

Thanks so much Gary! Sorry for the late reply.
