This document contains 5 questions about raster systems and frame buffers: 1) It asks for the frame buffer size in bytes needed to store 12 and 24 bits per pixel for raster systems with resolutions of 640x480, 1280x1024, and 2560x2048. 2) It asks for the number of pixels that can be accessed per second and the access time per pixel for raster systems with resolutions of 640x480 and 1280x1024 refreshing at 60Hz. 3) It asks for the raster size in bytes needed to store 4 and 8 bits per pixel for a 1024x1024 raster system. 4) It asks how much time is spent scanning each row of pixels for a 1280x1024 system
