Homework 4

Due Sept. 17

  1. RAID level 3 is able to correct single-bit errors using only one parity drive. What is the point of RAID level 2? After all, it also can correct only one error and takes more drives to do so.
  2. A bit-map terminal has a 1920 1080 display. The display is redrawn 75 times a second. How long is the pulse corresponding to one pixel?
  3. A high-end digital camera has a sensor with 24 million pixels, each with 6 bytes/pixel. How many pictures can be stored on an 8-GB flash memory card if the compression factor is 5x? Assume that 1 GB means 230 bytes.
