2. To give the copyright holder protection from their work being copied or stolen

Question 3

In each case the developer or owner of the website must either

Answer 3

own the copyright themmselves
seek permission to use the content from the copyright owner
give credit for the use of content

Question 4

WAV files

Answer 4

uncompressed

high quality sound

standard for CDs

large file size

Question 4

MP3

Answer 4

Lossy Compression

Removes high and low frequencies generally not heard by human ear

compression results in file size around one tent of original

small file size

Question 5

JPEG

Answer 5

Lossy compression

24 bit colour depth

No animation

No transparency

Used to store photographs

Question 6

GIF

Answer 6

Lossless compression

8 bit colour depth

Animation

Transparency

Not suitable for photographs, good for cartoons and animations

Question 7

PNG

Answer 7

Lossless compression

24 bit colour depth

No animation

Transparency

Used to store photographs

Question 8

what is resolution

Answer 8

the total number of pixels in the image

Question 9

Lower the resolution

Answer 9

-lower image quality
-smaller file size

Question 9

Higher the resolution

Answer 9

• better the image quality
  -larger file size

Question 10

What is colour depth

Answer 10

The measure of the number of bits used to store the colour for each pixel in an image

Question 10

8 bit colour depth

Answer 10

256

Question 11

16 colour bit

Answer 11

65,536

Question 12

24 bits

Answer 12

16,772,216

Question 13

The higher the colour depth

Answer 13

better image quality
larger file size

Question 14

The lower the colour depth

Answer 14

lower image quality
smaller file size

Question 15

what is sample rate

Answer 15

a measure of how many times per second a sound is sampled

Question 16

Higher sample rate

Answer 16

better audio sample
larger file size

Question 17

Lower the sample rate

Answer 17

lower the audio sample
smaller file size

Question 18

what is the purpose of compression

Answer 18

to reduce the size of a file

Question 19

what will a compressed file do

Answer 19

download quickly
stream quicker
takes up less space in memory

Question 20

Lossless compression

Answer 20

None of the original data is lost

file tends to be larger compared to lossy compression

Question 21

Lossy compression

Answer 21

some of the original data is lost although compression algorithms attempt to minimise the loss of quality

file tends to be smaller compared to lossless compression

Question 22

what is a low fidelity prototype

Answer 22

a sketch of the proposed web page with more detail than the wireframe

Question 23

A low fidelity prototype will include

Answer 23

any actual heading and paragraph text

sketched versions of any images or video

Question 24

purpose of a low fidelity prototype

Answer 24

test navigation
show the intended look to the user
allows the end user to request additional functionality
