Display Adapters
All these display adapters have text modes in which each character cell contains an 8-bit character code point (see details), giving 256 possible values for graphic characters. This way, beyond the original ASCII graphical character set (values 32 to 126, 95 in total), the implementers put in ROM a handful of miscellaneous characters even for the range 0 to 31, reserved in ASCII for control (non graphical) purposes.

Famous quotes containing the word display:
“We rarely quote nowadays to appeal to authority ... though we quote sometimes to display our sapience and erudition. Some authors we quote against. Some we quote not at all, offering them our scrupulous avoidance, and so make them part of our “white mythology.” Other authors we constantly invoke, chanting their names in cerebral rituals of propitiation or ancestor worship.”
—Ihab Hassan (b. 1925)
