Q

unicode

A

supports international languages

allows for 16 bits per character

20
Q

read/write head

A

a storage device requires a scan across the surface of a spinning disk to record and/or access data and information

21
Q

track

A

a concentric circular band around the disk that is dividend into pie shaped wedges called sector

22
Q

cluster

A

more than one sector

23
Q

file allocation table (FAT)

A

serves as table of contents for the disk that allows the read/write head to identify where to store or access data and information

24
Q

new technology file system (NTFS)

A

Microsoft Windows 10 version of FAT

25
Q

storage characteristics

A

most important aspect of data/information
how much data it can hold (capacity of storage media)
how long does it take to write the device
how long does it take to read the device (access time)

26
Q

floppy disk

A

non-volatile, very thin flexible magnetic storage disk that rotates inside a square plastic shell
1.44 Mb

27
Q

hard disk drive

A

non-volatile, rapidly rotating platters with magnetic surfaces (internal and cannot be removed mainly) (external can be removed and valued for their portability)
40 Gb-50 Tb

28
Q

flash memory/USB flash thumb drive

A 
non-volatile, primarily used in memory cards for digital cameras and thumb drives
flash memory (solid state, no moving parts)
256 Mb-2 Tb
29
Q

CD, CD-R, CD-RW

A

non-volatile, a compact disk, an optical disc used to store digital data
remain the standard medium for commercial audio recordings
600 Mb-1 Gb

30
Q

DVD (digital versatile disc)

A

non-volatile, optical disc like a CD, but used to deliver high-definition movies and sound
15 Gb-30 Gb

31
Q

Blu-Ray

A

non-volatile, high-density optical disc for storing high definition videos
25 Gb-30 Gb

32
Q

magnetic tape

non-volatile, sequential access, packaged on reel-to-reel cartridges like cassette tapes, very slow access, very inexpensive, used extensively for mainframe and backing up
unlimited capacity

33
Q

Redundant Array of Inexpensive Disks (RAID)

A

a series of stacked, spinning hard disk platters connected together that divide and replicate data and information to provide more reliable storage
unlimited capacity

34
Q

mass storage

A

large amounts of data and information

unlimited capacity

35
Q

cloud storage

A

essentially a hard drive that resides on the internet, the cloud will revolutionize business computing
unlimited capacity

36
Q

capacity

A

amount of data and information a storage device can hold

37
Q

access time

A

the amount of time needed to get data and information from a storage device

38
Q

compare PCs and magnetic tape for access time

A

PCs, faster access time, more expensive

magnetic tape, sequential access, slow, cheaper

39
Q

advances in technology

A

storage devices are growing exponentially in capacity and dropping quickly in price

40
Q

holographic storage

A

stores information in a three dimensional photopolymer

41
Q

molecular storage

A

very small and relies upon special chemicals to change the state of a single molecule from a positive charge to a negative charge

42
Q

archiving

A

data is no longer used on a daily basis and is stored electronically because it may be used at a later date

43
Q

data backup

A

copying of computer files that can be restored in the event that the original files are lost

44
Q

archiving and backup strategies

A 
cost
location
type of data
time
how often
data security
disaster recovery
45
Q

corruption

A

when errors occur in data retrieval or transmission and the original data contains unintended changes or is altogether unstable

46
Q

Disaster Recovery Plans (DRPs)

A

critical plans in place to anticipate disasters and outline what needs to be done they occur
