Question 1.
What is the definition of bit density?
Show hintHide hint
Think about how tightly data can be packed on the disk.
Question 2.
What does constant angular velocity mean?
Show hintHide hint
Consider the speed of a tire on a moving car.
3Question 3.
What does bit density refer to?
- How much time it takes to access data
- How much information can be stored in a disk
- The speed of the disk rotation
Show hintHide hint
Think about storing data on disk tracks.
4Question 4.
True or False: Zones are beneficial for optimizing bit density?
- True
- False
Show hintHide hint
Consider how organization affects storage space.
Question 5.
You have a disk with 4 zones. If the outer zone holds 1000MB, and each subsequent inner zone holds 50% less, what is the total capacity of the disk?
Show hintHide hint
Consider how much data each zone holds and sum them up.
Question 6.
A disk has two types of data: critical and standard. If critical data occupies 30% of the total disk space and standard data occupies the rest, how much space is allocated to standard data on a disk of 500GB?
Show hintHide hint
Calculate what percentage remains after allocating the critical data.
