Hard drives are nearly always external devices.
The process of storing information on storage media
is called writing
All hard drives have one read/write head on the top and one on the bottom of each platter.
If a read/write head collides with the surface of a disk, this is called a head crash.
Some hard drives can spin at rates as high as 120,000 revolutions per minute.
Solid state disks store data using flash memory.
Flash memory drives work faster than magnetic drives.
A USB flash drive has several moving parts.
Data on a flash drive is protected by a hard plastic or metal case.
When the write-protect switch is "on," the computer can write to it but it cannot delete data already on it.
USB flash drives require battery power.
A PhotoCD is an example of a magnetic storage medium.
To read data from an optical disc, a drive shines a laser beam on the disc and a laser sensor reads changes in the physical properties of the disc.
Because a pit scatters laser light instead of reflecting it, it represents a data bit of 0.
This is a hard drive's main function.
Within a hard drive, these are the storage media.
The surfaces of a hard drive's platters are divided into a set of circles, called ________.
When you no longer need information stored on a hard drive, you can do this to it.
In a hard drive, these components store and retrieve data on the platters.
A hard drive stores data by creating these on the surface of its platters.
The speed at which a hard drive's platters spin is measured in ________.
What does the term SSD stand for?
What type of memory does a USB flash drive use?
Flash memory drives store data on a ________.
A ________ allows a USB flash drive to read, write and erase data on the drive.
This is used to keep data from being written or deleted on a USB flash drive.
When data is damaged or made unusable, a storage device experiences this.
All of the following are used to help prevent data loss EXCEPT ________.
Which of the following is an example of an optical storage device?
When discussing optical media, some people change the spelling of disk to this.
A CD-ROM drive's speed is measured as a multiple of this number.
On the reflective surface of an optical disc, this represents the binary number 1.
Which of the following optical devices is a read-only device?
Which of the following is NOT a common storage-device problem?
