Question

Картинку размером 1024x768 передали через некое соединение со скоростью v=256 бит в секунду. Рассчитать время, за которое была передана картинка, и информационный объем изображения, если известно, что количество цветов в палитре 1024 Заранее спасибо

Answer 1

Obem=1024*768=786432 pixel
skorost=256/8=32 bayt
pix=2^10=1024=10 bayt
time=(10*786432)/32=7864320/32=24576 sec.
RESULT=24576sec.

Answer 2

Calculating Transmission Time and Information Volume of an Image

To calculate the time it takes to transmit the image and the information volume of the image, we can use the formula:

Transmission Time (T) = Image Size / Transmission Speed Information Volume = Image Size * Number of Colors

Given: - Image size: 1024x768 - Transmission speed: v = 256 bit/s - Number of colors in the palette: 1024

Calculating Transmission Time

First, we need to calculate the size of the image in bits.

The size of the image in bits can be calculated using the formula: Image Size = Width x Height x Number of Bits per Pixel

For a typical image, each pixel is represented by 24 bits (8 bits for each of the Red, Green, and Blue color channels).

So, the size of the image in bits would be: Image Size = 1024 x 768 x 24

Let's calculate the image size: Image Size = 1024 x 768 x 24 = 18874368 bits

Now, we can calculate the transmission time: Transmission Time (T) = Image Size / Transmission Speed T = 18874368 bits / 256 bit/s

Calculating the transmission time: T ≈ 73704 seconds

So, the time it takes to transmit the image is approximately 73704 seconds.

Calculating Information Volume

Now, let's calculate the information volume of the image.

The information volume is given by: Information Volume = Image Size * Number of Colors Information Volume = 18874368 bits * 1024

Calculating the information volume: Information Volume ≈ 19327314944 bits

So, the information volume of the image is approximately 19327314944 bits.

Therefore, the time it takes to transmit the image is approximately 73704 seconds, and the information volume of the image is approximately 19327314944 bits.
