Digital Information: Bits and Bytes + Binary Numbers

Question 1

Binary Data

Answer 1

1s and 0s

Question 2

What parts of a computer contain all the info

Answer 2

wires + circuits

Question 3

How is information stored in computers using electricity

Answer 3

using bits

Question 4

Bit

Answer 4

the smallest piece of information a computer can store

Question 5

What are Bits made of

Answer 5

(2 options) 0s OR 1s
BITS ONLY HOLD ONE PIECE OF INFO

Question 6

Bits are stored in what

Answer 6

wires

Question 7

How many bits are in 1 wire

Answer 7

1 ( a 0 and 1)

Question 8

The binary number system

Answer 8

only 2 digits: 0 and 1 where each position multiplies by 2

(so like instead of ones position, tenths position, hundredths position, etc. you get ones position, twos position, fourth position, etc.)

Question 9

how can you calculate a number with 1s and 0s

Answer 9

multiply 1 or 0 by the exponent number thingie whatever place its in

Question 10

how do you calculate the binary system numbers of 1001

Answer 10

(12^3) + (02^2) + (02^1) + (12^0) = 9

Question 11

How are texts represented with binary Data

Answer 11

assign numbers (and therefore binary thingies)

Question 12

How are images represented with binary Data

Answer 12

pixels that have colors that are represented with different numbers

Question 13

sound

Answer 13

a series of vibrations in the air

Question 14

how is sound represented in binary Data

Answer 14

each point on a graph of a sound waveform is represented by a different set of binary Data

Question 15

when sound is recorded in a graph what is it called

Answer 15

a sound waveform

Question 16

higher quality sound has ____ (more/less) bits

Answer 16

more

Question 17

What does a single bit represent

Answer 17

two different values (can be on or off, red or yellow, etc.etc.)

Question 18

Which of the settings can be stored in a single bit?
User name – type in
Birthdate – drop down
Primary language – drop down
Sound effects – check box

and why

Answer 18

sound effects bc they’re either on or off

Question 19

how do you determine how many different ways a set of bits can be interpreted

Answer 19

do 2 to the power of how many bits there are because each bit has 2 different options

Question 20

Binary digit

Answer 20

represents either the value 0 or 1

Question 21

Byte

Answer 21

a unit of digital information that consists of 8 bits

Question 22

how to convert from bits to bytes

Answer 22

multiply by 8

Question 23

how to convert from bytes to bits

Answer 23

divide by 8

Question 24

why is there a specific name for bytes

Answer 24

because computers like to process bits in groups of 8 and they are also the smallest addressable memory unit of memory in most modern computers

Question 25

if a computer has byte addressable memory can it store memory in a single bit

Answer 25

no

Question 26

nibble

Answer 26

4 bits

Question 27

byte

Answer 27

4 bits

Question 28

crumb

Answer 28

2 bits

Question 29

Hint for writing binary numbers that are odd

Answer 29

the last digit always has to be a 1

Question 30

formula for highest number that can be represented by a certain AMT of bits

Answer 30

2^n - 1
