Question 2.
What is a sector?
Show hintHide hint
Relate it to how disks save information.
3Question 3.
What is bit density?
- Data size per unit area
- Speed of data retrieval
- Type of storage medium
Show hintHide hint
Consider what it means to pack data closely together.
4Question 4.
true or false: Sector size affects how data is read and written on a disk.
- True
- False
Show hintHide hint
Think about how data is grouped on the disk.
Question 5.
A hard drive has 1000 sectors on an inner track and 500 on an outer track, with each sector holding 512 bytes. Calculate the total data capacity for both tracks and analyze the efficiency of their spacing.
Show hintHide hint
Use multiplication for capacity and compare densities.
Question 6.
If a disk's formatting allows it to change sector sizes, how might increasing the sector size affect the overall disk performance and efficiency? Discuss potential trade-offs.
Show hintHide hint
Think about file size and how it relates to sector size.
