CNIT 242 STORAGE QUESTIONS & ANSWERS
Block Devices are...
Physical Devices: Ex. Hard Drive, SSD, Optical Drives, RAID arrays, SANs
File Containers are...
Logical Devices: Ex. Formatted Partition
Examples of SANs
Fiber Channel, iSCSI, AON
Examples of Optical Drives
CD, DVD, Blu-Ray
Disks may be numbered starting with a 0 or 1 depending on the system. True of False
True
Each Platter is referenced by top and bottom what?
Sides or Heads (Starts with 0)
What is the name for the concentric circles where data is stored?
Tracks (Starts with 0)
There are multiple platters per drive. True or False
True (Starts with 0)
What do identically numbered tracks on all the platter surfaces make up?
Hollow Cylinder: Can be written without movement of the head assembly and is
numbered starting with 0
What is 1/8 of a track referred to?
, Sector: a continuous linear stream of magnetized bits occupying a curved section of a
track. NUMBERING START WITH 1
Sectors are the BIGGEST physical storage units on a disk. True of False
False: Sectors are the smallest, each sector contains 512 Bytes of data
A sector will always be 512 bytes for a DOS/Windows. True or False
True: Even with variation in the number of tracks or heads
Can we use Cylinder, Head, and Sector to find a 3-D coordinate for data?
Yes, the method is referred to as CHS.
Ex. Cylinder 4, Head 4, Sector 4
How many sectors are there to a cluster?
8 sectors & 4096 Bytes (512*8)
Only 1 file can be stored in a cluster but a file can occupy more than one cluster. True
or False
True
Logical Block Addressing (LBA) addresses the sectors as a continuous linear stream
and numbers them accordingly. But where does the numbering begin?
The first physical sector on the disk
Do file systems hold fixed or variable length files?
Variable Length
Do Record/Page/Block systems hold fixed or variable length data?
Fixed length
A file system is an alphabetical system of files and their respective directories. True or
False
False, it is a hierarchal system
Is a physical disk one partition?
No, it is broken into multiple partitions
