Question

Модем передаёт данные со скоростью 7680 бит/с. Передача текстового файла заняла 1,5 мин. Определите сколько страниц содержал переданный текст если известно что он был представлен в 16-битной кодировке Unicode, а на одной странице - 400 символов

Answer 1

весь текст К бит К=7680 бит/с.* 90с =691200 бит

всего символов С  С=691200 бит/16бит=43200

всего страниц  Ц  =Ц=43200/400=108 с

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 transmission speed of the modem, the time it took to transfer the text file, and the encoding of the text.

Given information: - Transmission speed: 7680 bits/s - Time taken to transfer the text file: 1.5 minutes - Encoding of the text: 16-bit Unicode - Number of characters per page: 400

To calculate the number of pages, we can follow these steps:

1. Convert the time taken to transfer the text file from minutes to seconds: - 1.5 minutes = 1.5 * 60 seconds = 90 seconds

2. Calculate the total number of bits transferred: - Total bits transferred = Transmission speed * Time taken - Total bits transferred = 7680 bits/s * 90 seconds = 691,200 bits

3. Convert the total number of bits to the number of characters: - Since the text is encoded in 16-bit Unicode, each character occupies 16 bits. - Total characters transferred = Total bits transferred / 16 - Total characters transferred = 691,200 bits / 16 = 43,200 characters

4. Calculate the number of pages: - Number of pages = Total characters transferred / Number of characters per page - Number of pages = 43,200 characters / 400 characters per page = 108 pages

Therefore, the transferred text contained 108 pages.
