Question

Передача текстового файла по каналу связи со скоростью 128000 бит/с заняла 1,5 мин. Определите, сколько страниц содержал переданные текст, если известно, что он был представлен в 16-битной кодировке Unicode, а на одной странице-400 символов.

Answer 1

N=vt;
N = 128000 бит/с *  90 с = 11520000 бит - вес файла.
16 бит * 400 симв = 6400 бит - вес одной страницы.
11520000/6400 = 1800 стр.
Ответ: 1800

Answer 2

Calculation of the Number of Pages in the Transferred Text

To determine the number of pages contained in the transferred text, we need to consider the following information:

- Transmission speed: 128,000 bits per second. - Transmission time: 1.5 minutes. - Text encoding: 16-bit Unicode. - Number of characters per page: 400.

To calculate the number of pages, we can use the following formula:

Number of Pages = (Total Number of Bits Transferred) / (Bits per Character) / (Characters per Page)

Let's calculate the number of pages using the given information:

1. Calculate the total number of bits transferred: - Transmission speed: 128,000 bits per second. - Transmission time: 1.5 minutes. - Convert the transmission time to seconds: 1.5 minutes * 60 seconds/minute = 90 seconds. - Total number of bits transferred = Transmission speed * Transmission time = 128,000 bits/second * 90 seconds = 11,520,000 bits.

2. Calculate the number of characters in the transferred text: - Text encoding: 16-bit Unicode. - Total number of characters = Total number of bits transferred / Bits per Character = 11,520,000 bits / 16 bits/character = 720,000 characters.

3. Calculate the number of pages: - Number of characters per page: 400. - Number of pages = Total number of characters / Characters per Page = 720,000 characters / 400 characters/page = 1,800 pages.

Therefore, the transferred text contained approximately 1,800 pages.
