Question

Объем видеопамяти равен 2,5 Мбайта, глубина цвета — 16, разрешающая способность экрана монитора — 960×640 точек. Найти максимальное количество страниц, которое можно использовать при этих условиях.

Answer 1

$2^n=16=>n=4\\2.5MeB*1024^2*8=20971520\ bit\\\frac{20971520\ bit}{(4*960*640)\ \frac{bit}{page}}=8\ pages$
8 страниц 

Answer 2

Calculation of Maximum Number of Pages

To calculate the maximum number of pages that can be used with the given conditions, we need to consider the video memory size, color depth, and screen resolution.

Given: - Video memory size: 2.5 MB - Color depth: 16 - Screen resolution: 960x640 pixels

To calculate the maximum number of pages, we need to determine the amount of memory required for each page.

The formula to calculate the memory required for each page is as follows:

Memory Required for Each Page = (Screen Resolution * Color Depth) / 8

Let's substitute the given values into the formula:

Memory Required for Each Page = (960 * 640 * 16) / 8

Simplifying the equation:

Memory Required for Each Page = 1228800 bytes

Now, we can calculate the maximum number of pages by dividing the total video memory size by the memory required for each page:

Maximum Number of Pages = Video Memory Size / Memory Required for Each Page

Substituting the given values:

Maximum Number of Pages = 2.5 MB / 1228800 bytes

Converting the video memory size to bytes:

2.5 MB = 2.5 * 1024 * 1024 bytes = 2621440 bytes

Maximum Number of Pages = 2621440 bytes / 1228800 bytes

Calculating the result:

Maximum Number of Pages ≈ 2.13

Therefore, the maximum number of pages that can be used with the given conditions is approximately 2 pages.
