Question

Книга содержит на каждой странице по 60 строк, в среднем по 50 символов в строке. Используется 16-битная кодировка. Для хранения книги понадобилось 1758 Кбайт памяти. Сколько страниц в книге?(можно приближенное число)

Answer 1

Ответ:

В книге 300 страниц.

Объяснение:

Дано:

Строк/страница = 60

Символов/строка = 50

i = 16 бит/символ

I = 1758 Кбайт = 1758 * 1024 * 8 бит = 14401536 бит

Найти: кол-во страниц

Решение:

I = K * i

14401536 бит = 60 * 50 символов * страницы * 16 бит/символ

страницы = 14401536 / (60 * 50 * 16) ≈ 300

Ответ: 300 страниц.

Answer 2

Calculation of the Number of Pages in the Book

To calculate the number of pages in the book, we need to consider the following information:

- Each page contains 60 lines. - On average, each line contains 50 characters. - The book uses a 16-bit encoding. - The book requires 1758 kilobytes (KB) of memory for storage.

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

1. Calculate the total number of characters in the book: - Each line contains 50 characters. - Each page contains 60 lines. - Therefore, each page contains 50 * 60 = 3000 characters.

2. Calculate the total number of bytes in the book: - The book requires 1758 kilobytes (KB) of memory for storage. - 1 kilobyte (KB) is equal to 1024 bytes. - Therefore, the book requires 1758 * 1024 = 1,798,272 bytes.

3. Calculate the total number of characters in the book: - The book uses a 16-bit encoding. - Therefore, the total number of characters in the book is equal to half of the total number of bytes. - The total number of characters is 1,798,272 / 2 = 899,136 characters.

4. Calculate the total number of pages in the book: - Divide the total number of characters by the number of characters per page. - The total number of pages is 899,136 / 3000 = 299.712 pages.

Since we cannot have a fraction of a page, we can approximate the number of pages in the book to the nearest whole number. Therefore, the book contains approximately 300 pages.
