Question

реферат имеет объём 60 листов на каждой странице 50 строк в среднем в каждой сторке 80 символов определите информационный объём реферата в кодировке виндоус 1251 и юникод ответ дайте в байтах и Кбайтах

Answer 1

60 листов * 50 строк * 80 символов = 240000 символов - всего в тексте
Кодировка Windows-1251 ( вес одного символа 8 бит ) - 240000 * 8 = 1920000 бит = 240000 байт = 234 КБайт
Кодировка Unicode ( вес одного символа 16 бит ) - 240000 * 16 = 3840000 бит = 480000 байт = 469 КБайт

Answer 2

Calculation of Information Volume in Windows-1251 Encoding

To calculate the information volume of a 60-page research paper, with 50 lines per page and an average of 80 characters per line, in the Windows-1251 encoding, we need to consider the number of bytes required to represent each character.

The Windows-1251 encoding uses a single byte to represent each character, allowing for a total of 256 possible characters. Therefore, each character in the research paper will require 1 byte of storage.

To calculate the information volume, we need to multiply the number of characters by the number of bytes required to represent each character and then convert the result to kilobytes (KB).

Let's perform the calculation:

Number of characters per page: 50 lines * 80 characters = 4000 characters Number of characters in the research paper: 4000 characters per page * 60 pages = 240,000 characters Number of bytes in the research paper: 240,000 characters * 1 byte = 240,000 bytes Number of kilobytes in the research paper: 240,000 bytes / 1024 = 234.375 KB (rounded to three decimal places)

Therefore, the information volume of the research paper in the Windows-1251 encoding is approximately 234.375 KB.

Calculation of Information Volume in Unicode Encoding

To calculate the information volume of the same research paper in Unicode encoding, we need to consider that Unicode uses multiple bytes to represent each character. The most common encoding for Unicode is UTF-8, which uses variable-length encoding.

The exact number of bytes required to represent each character in Unicode depends on the specific characters used in the research paper. However, on average, UTF-8 encoding requires 2 to 4 bytes per character.

To provide an estimate, let's assume an average of 3 bytes per character in the research paper.

Let's perform the calculation:

Number of bytes in the research paper: 240,000 characters * 3 bytes = 720,000 bytes Number of kilobytes in the research paper: 720,000 bytes / 1024 = 703.125 KB (rounded to three decimal places)

Therefore, the information volume of the research paper in Unicode encoding (assuming an average of 3 bytes per character) is approximately 703.125 KB.

Please note that the actual information volume in Unicode encoding may vary depending on the specific characters used in the research paper.
