QUESTIONS AND ANSWERS SURE A+
✔✔To increase capacity per platter, disk manufacturers divide tracks into two or more
zones and vary the sectors per track in each zone.
True or False - ✔✔T
✔✔Computing average access time is more complex when sectors are more densely
packed on the platter's outer portions because the assumption that an average access
requires moving the read/write head over half the tracks is no longer valid.
True or False - ✔✔T

commonly encountered with portable devices, such as multifunction cell phones,
netbooks, and laptop computers.
True or False - ✔✔T
, ✔✔Magnetic disk drives have an advantage over SSDs in power consumption.
True or False - ✔✔F
✔✔Most optical storage media can retain data for decades because they aren't subject
to magnetic decay and leakage.
True or False - ✔✔T
✔✔Magnetic hard disks typically have access times under 5 ms.
True or False - ✔✔???
✔✔Magnetic and optical storage are currently direct competitors.
True or False - ✔✔F
