How many bits per pixel are needed to represent 256 colors?
To represent 256 colors it is needed 8 bit per pixel. 1 bit mean 2 colors, 2 bits mean 4 colors, 3 bits per pixel can represent 8 colors... 8 bits = 256 colors.
There are 2 colors in bits per pixel - 4 colors in 2 bits per pixel - 16 colors in 4 bits per pixel and similarly this sequence continuous going on.
A color images uses 16bits to represent a pixel what is the maximum number of different colors that can be represented?
The number of different colors you can represent with 16 bits is 216, or about 65,000 colors.
Using 8 bits per pixel, how can represent 256, or 28 shades
You can represent a maximum of 2^24 colors in RGB. This equals to 16777216 possible colors.

256, 8 bits per pixel = 2^8 colours.
You are actually asking how many colors are possible in 8 bit per channel. 8 bit per channel means 256 colors, 1 bit= 2 colors, 2 bits= 4 colors, 3 bits= 8 colors, 4 bits= 16... 8bits= 256 colors. Since we have 3 channels in RGB color mode: Red, Green and Blue that means that we have 3x8= 24 bits per pixel in an image. 3x8 also means 256x256x256 colors possible. Number of possible colors… Read More
A "black and white" image is generally actually a grayscale image, which is typically represented with 8 bits per pixel. However, you can make images that use only one bit per pixel, making each pixel either fully black or fully white. The images created by the early graphics software MacPaint used only one bit per pixel.
A 32 bit per pixel bitmap will have 8 bits each for red green and blue, and 8 bits for alpha level. So 2^24 colors.
8 bits if unsigned, 9 bits if signed
Direct coding of RGB values with 10 bits per primary color how many possible colors do you have for each pixel?
2^10 = 1024 possible colors per each channel (R for example). Then 2^30 for a pixel. This makes 1024^3 = 1073741824 possible different colors for a pixel.
Typical uncompressed colored images use 24 or 32-bits per pixel of an image (RGB 8-bits per color). After some basic math of lets say an 8 Megapixel image quickly becomes a very large file on a computer. A type of compression used is to select some colors (typically called a palette) and for every pixel in the original image select a color in the palette that is closest to it (some other techniques exist to… Read More

Compression is a reduction in the number of bits needed to represent data.
45 in binary is 101101, so you need at least 6 bits to represent 45 characters.
formula to find compression ratio when bits per pixel is given
Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.
1024bits If "Bitmap" refers to a specific entity, image or file: I do not know. But if "Bitmap" refers to a general image then it is 8 bytes or 64 bits per pixel. I just made 3 1*1 bitmap images at colordepths 2bits (monochrome), 8 bits (256 colors) and 24 bits (16 Million colors). The sizes of these images were the same! (surprized me too!) Then I made a 1*2 pixel image and it was… Read More
log2 200 = ln 200 ÷ ln 2 = 7.6... → need 8 bits. If a signed number is being stored, then 9 bits would be needed as one would be needed to indicate the sign of the number.
18 in binary is 10010 Since 18 can't be written in term of 2 to the power x, the number of bits needed is 5. The answer is 5
24 bits/pixel: one byte for red, one byte for green, one byte for blue.
If you mean "64 different characters", you need log2(64) = 6 different bits.
That depends on how many bits per pixel and how much the image is compressed. For example, a black-and-white (grayscale) image typically has 8 bits per pixel, but a full-color image may have 24 or 32 bits per pixel. JPEG compression may reduce the file size dramatically, sometimes by a factor of 50 or more.
No, they are shape based and do not have pixel bits.
The answer depends on the precision required for the numbers.
If you consider that there are two possibilities for each byte, then taking two to the eighth power gives you 256 different possibilities. If you mean there are a total of 24-bits, then you can take 2 to the 24th power to get the answer, or you can take 256 to the 3rd power. Either way, that should represent about 16.7 million possibilities.

A bitmap for an electronic image is a specification of the space occupied by the image and information about the colour of each dot (pixel) in it.
A computer monitor has a resolution of 1300 by 1000 pixels if each pixel uses 1024 colours how many bits are needed to send complete contents of screen?
1300 x 1024 = 13312ooooo
8 (assuming unsigned numbers - i.e., you don't reserve a bit for the sign).

23 can be represented in binary as 10111 and would therefore require 5 bits to represent.
How long would it take to load a 640 by -480 frame buffer with 12 bits per pixel if 105 bits can be transfered per seconds?
Assuming 12 bits for each pixel, rather than per color. The 105 bit per second sounds kind of slow, though. A 640 x 480 = 307,200 pixels. Multiply by 12 bits = 3,686,400 bits. So divide by 105 bits per second = 35,109 seconds, or about 9 hours 45 minutes.
Binary bits are necessary to represent 748 different numbers in the sense that binary bits are represented in digital wave form. Binary bits also have an exponent of one.
4 bits. 24 = 16, so you have 16 different combinations. 4 bits. 24 = 16, so you have 16 different combinations. 4 bits. 24 = 16, so you have 16 different combinations. 4 bits. 24 = 16, so you have 16 different combinations.
A hex color is represented by three different levels of the RGB (Red, Green and Blue) colours. Each of which is given a level of shade. To represent this the colors usually have a hexadecimal value for each of the RGB which is made up of two numbers each ranging from 0-f so ff would represent completely on. If you were to have all three red, green and blue completely on or ffffff then you… Read More

Standard ascii uses 7 bits, but usually a byte (8 bits) is used.
