CS 601 - Chapter 7 with
100% correct answers 2024
Primary Storage - answer Before data can be processed or a
program can be run, it must be in RAM. RAM is sometimes referred
to as this.
Secondary Storage - answer Provides permanent or nonvolatile
storage.
Secondary Storage Devices - answer Such as a hard-disk drive,
data and programs can be retained after the computer has been
shut off. This is accomplished by writing files to and reading files
from these.
Media - answer Important part of secondary storage. The actual
physical material that holds the data and programs.
Capacity - answer Important part of secondary storage. Measures
how much a particular storage medium can hold
Storage Devices - answer Important part of secondary storage.
Hardware that reads data and programs from storage media. Most
also write to storage media
Access Speed - answer Important part of secondary storage.
Measures the amount of time required by the storage device to
retrieve data and programs.
Density - answer Refers to how tightly charges can be packed next
to one another on the disk.
, Hard Disks - answer Store and organize files using tracks, sectors,
and cylinders. Use platters that are stacked one on top of another
Tracks - answer Rings of concentric circles without visible grooves.
Sectors - answer Each track is divided into invisible wedge-shaped
sections called this.
Cylinder - answer Runs through each track of a stack of platters.
These are necessary to differentiate files stored on the same track
and sector of different platters.
Head Crash - answer Occurs when a read/write head makes contact
with the hard disk's surface or with particles on its surface. This is a
disaster for a hard disk. Some or all of the data is destroyed.
Internal Hard Disk - answer Located inside the system unit. These
hard disks are able to store and retrieve large quantities of
information quickly. They are used to store programs and data files
External Hard Disk - answer Use the same basic technology as
internal hard disks an are used primarily to complement an internal
hard disk. Used to protect or secure sensitive information.
Disk Caching - answer Improves hard-disk performance by
anticipating data needs. It performs a function similar to cache
memory.
Redundant Arrays of Inexpensive Disks/RAID - answer Improves
performance by expanding external storage, improving access
speed, and providing reliable storage. Raid is often used by Internet
servers and large organizations.
