short answer

3. A bitmap image format uses 16 bits per pixel. How many bytes are needed to represent an uncompressed image that is 160 pixels by 120 pixels?

4.A high definition (HD) display with a resolution of 1920 by 1080 pixels uses 24 bit color. How many bytes of memory are required to hold a copy of the image that is displayed on the HD display?

5.If digital audio has a bit depth of 16, how many different amplitude levels can be represented?

Explanation / Answer

Multiple choice:

1) B--FALSE

2) A-```

3) Considering a RGB image (i.e. 3 color image), the total bytes required will b = (3 x 16 x 160 x 120)/8 = 115200 Bytes

4) Similarily for the given HD display = (3 x 24 x 1920 x 1080)/8 = 18662400 Bytes

5) For a bit depth of 16, the total amplitude levels represented will be= 216=65536

Hope this helps!
