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.
Information commination technology :)
1. It is based on scientific and technological advancements.
2. It is more a practical discipline and less a theoretical one.

Answer:
1100 ; 11000 ; 110000 ; 1100000
Explanation:
Converting the following decimals to binary :
2__12
2__6 r 0
2__3 r 0
2__1 r 1
___0 r 1
12 = 1100 base 2
2.)
2__24
2__12 r 0
2__6 r 0
2__3 r 0
2__1 r 1
___0 r 1
24 = 11000 base 2
2__48
2__24 r 0
2__12 r 0
2__6 r 0
2__3 r 0
2__1 r 1
___0 r 1
48 = 110000 base 2
2__96
2__48 r 0
2__24 r 0
2__12 r 0
2__6 r 0
2__3 r 0
2__1 r 1
___0 r 1
96 = 1100000 base 2
