A bitmap terminal contains 1280 by 960 pixels. To scroll a window, the CPU (or controller) must move all the lines of text upward by copying their bits from one part of the video RAM to another. If a particular window is 60 lines high by 80 characters wide (5280 characters, total), and a character”s box is 8 pixels wide by 16 pixels high, how long does it take to scroll the whole window at a copying rate of 50 nsec per byte? If all lines are 80 characters long, what is the equivalent baud rate of the terminal? Putting a character on the screen takes 5 psec. How many lines per second can be displayed? Wr
