    One reason GUIs were initially slow to be adopted was the cost of the hardware needed to support them. How much video RAM is needed to support a 25 line X 80 row character monochrome text screen? How much for a 1024 X 768 pixel 24-bit color bitmap? What was the cost of this RAM at 1980 prices ($5/KB)? How much is it now?

    Hello and thank you for posting your problem to Brainmass.

    There are 128 standard ASCII characters.

    While this means that essentially we need only 7 bits for the entire ASCII set, a standard ASCII character requires one byte (8 bits) of memory - the MSB is set to ...
