Question 1 5 pts A screen has a 5 x 7 rectangular grid of pixels for each character. It can display 24 rows of 80 columns of characters. (a) How many pixels are on the screen? (b) If each pixel is stored as one bit, how many KB does it take to store a screen image? Answer: a) There are pixels for each character There are characters on a screen Therefore, there are pixels on the screen b) From (a) we know how many pixels are on the screen. One pixel per bit, therefore BYTES on the screen This is KB ( one decimal place) Question 2 3 pts A desktop laser printer has a 300-pixel-per-inch resolution. If each pixel is stored in one bit of memory, how many bytes of memory are required to store the complete image of one 8.5 by 11 inch page of paper?
