The distance from earth to a distant planet is approximately 9 x 107 km. assume that the frame size is 16 kb and the speed of light is 3 108 m/s. assume that the bit rate is 20 mbps.

plot the efficiency versus the distance when the bit rate is set to 20 mbps. discuss this plot.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
