Question

Главный редактор журнала отредактировал статью, и её объём уменьшился на 4 страницы. Каждая страница содержит 32 строки, в каждой строке 64 символа. Информационный объём статьи до редактирования был равен 1 Мбайт. Статья представлена в кодировке Unicode, в которой каждый символ кодируется 2 байтами. Определите информационный объём статьи в Кбайтах в это варианте представления Unicode после редактирования.

Answer 1

I = i*M*N*K; K = I/(M*N*i) = 1 048 576/(32*64*2) = 256 страниц

256-4 = 252

I = 252*32*64*2 = 1032192байт = 1008Кб

Answer 2

Calculation of the Information Volume of the Article

To determine the information volume of the article in kilobytes (Kbytes) after editing, we need to consider the following information:

- The original article had a size of 1 Megabyte (MB). - Each page contains 32 lines. - Each line contains 64 characters. - The article is encoded in Unicode, where each character is encoded using 2 bytes.

To calculate the information volume, we need to calculate the number of characters in the article after editing and then convert it to kilobytes.

Calculation Steps:

1. Calculate the number of characters per page: - Each line contains 64 characters. - There are 32 lines per page. - Therefore, each page contains 64 * 32 = 2048 characters.

2. Calculate the number of pages removed during editing: - The article's volume decreased by 4 pages. - Therefore, 4 * 2048 = 8192 characters were removed.

3. Calculate the new number of characters in the edited article: - Subtract the number of removed characters from the original article's character count: - Original article size: 1 MB = 1,048,576 bytes. - Subtract 8192 characters (16,384 bytes) from the original size: 1,048,576 - 16,384 = 1,032,192 bytes.

4. Convert the new size to kilobytes: - Divide the new size in bytes by 1024: - 1,032,192 / 1024 = 1008 Kbytes.

Therefore, the information volume of the article in Kbytes after editing is 1008 Kbytes.
