If an image has only 4 colors, how many bits are necessary to represent one pixel’s color? Describe a new custom encoding that u

ses fewer bits to represent each color in the image. What is your encoding for each color? If you were to re-encode this image using your new encoding, how many bits would you save when compared to the 24 bit RGB encoding?

Answer:

1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)

Explanation:

As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:

00 = color 1

01 = color 2,

10 = color 3,

11 = color 4

This would be the custom type of encoding for that specific image as it only uses 4 colors.

Now to calculate the amount of memory saved, which is quite simple:

24-2=22

So you Would save 22 bits per pixel or 2.75 bytes per pixel.

REY [17]

Answer:

16.

Explanation:

A Nibble has four bits.These are binary bits that consists of 0 and 1 only.So the different codes it can represent are started from 0000 and to 1111.Each code corresponds to a single character only.The number of characters it can represent are 2*2*2*2=16. So the number of different characters represented are 16.

How can we compare a computer with human beings?
LenaWriter [7]

Answer:

Our brain as a central information processor vs. computer having a central processing unit

Our brain takes sensory input → processing/ sense making → in order to produce behavior as output. Computers work similarly: information input → processing → output task

Computers requires both hardware and software to function. Our body is essentially hardware, what we learn from formal education and informal life experiences are software.

Why do bats sleep upside down
seraphim [82]

Answer:

Bats cannot run so it would be almost impossible for them to take off from the ground. A major advantage to hanging upside down is that bats do not need to generate lift to begin flight. They just drop out of their bed, open their wings and off they go.
