Exam 5: Data Storage Technology

Current SSDs use ____ as the storage medium.

A ____ reorganizes disk content so that a file's contents are stored in sequential sectors, tracks, and platters.

Magnetic and optical storage are currently direct competitors.

A storage device or medium is ____ if it holds data without loss over long periods.

In a magneto-optical drive, the laser polarity shift used in reading is known as the "____________________ effect."

​The ____ is the device or substance that actually holds data.

____ stores each bit by using a single transistor and capacitor.

____________________ is the time required to perform one complete read or write operation.

Communication channel capacity is generally a restriction on a single disk drive's data transfer rate.

In a magnetic disk drive, a(n) ____________________ is mounted on the end of an access arm for each platter surface.

Storage device speed is called ____.

Modern SSDs use a technique called "____" to spread write operations around the storage medium, thus evening out the impact of destructive writes and extending the storage device's useful life.

A ____ consists of all tracks at an equivalent distance from the edge or spindle on all platter surfaces.

Magneto-optical technology peaked in the mid-1980s.

Primary storage devices must closely match CPU speed and word size to avoid ____________________.

Capacitors can charge and discharge much faster than batteries.

For a two-dimensional storage medium like a disk platter, having the length and width of the area that stores one bit increases storage capacity by a factor of ____________________

In a CD, flat areas in the reflective layer that represent bit values are called "____."

____________________ is a read-ahead RAM that uses the same clock pulse as the system bus.

____________________ RAM is the most common non-volatile RAM used today.
