Question 9

primary storage

Answer 9

what a user is currently working on

Question 10

secondary storage

Answer 10

where the user stores their work when they are finished
non-volatile
not directly accessible by the CPU
must make use of the input/output channels
slower than primary storage, but higher capacity

Question 11

random access memory (RAM)

Answer 11

primary storage that is temporary and volatile
can be accessed in any order
if computer loses power while contents are in RAM and not in secondary storage, contents will be lost

what is the bit with a positive charge

Answer 14

a 1 bit

Question 15

what is the most common way to read and write to digital media?

Answer 15

a spinning magnetic disk with a “read/write” device (allows bits and bytes to stick to it)

Question 16

8 bits=

Answer 16

a byte

Question 17

American Standard Code for Information Interchange (ASCII)

Answer 17

coding scheme to represent characters internally
256 possible combinations of 8 bits
only 95 characters are printable

Question 18

Extended Binary Coded Decimal Interchange Code (EBCDIC)

Answer 18

larger computers, like IBM’s mainframes use these

Question 19

unicode

Answer 19

supports international languages

allows for 16 bits per character

Question 20

read/write head

Answer 20

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

track

Answer 21

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

Question 22

cluster

Answer 22

more than one sector

Question 23

file allocation table (FAT)

Answer 23

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

Question 24

new technology file system (NTFS)

Answer 24

Microsoft Windows 10 version of FAT
