Question

В книге 674 страницы, 60 символов в строке, 48 строк на странице. Необходимо вычислить информационный объем текстового документа в Мбайт ( с точностью до сотых ) и узнать, сколько дискет 3.5 дюйма объемом 1,44 Мбайт понадобится для переноса этого документа ид дома в издательство (наличием электронной почты и архиваторов пренебрегаем).

Answer 1

60 * 48 = 2880 - символов на 1 сранице
2880 *674 = 1941120 - символов в книге.
если ничего не говорится, то 1 символ кодируется 1 байтом, значит
в книге 1941120 байт
переводим в килобайты: 1941120/1024 = 1895,625 Кбайт
переводим в мегабайты: 1895,625/1024=1,85 Мбайт - информационный объем текста
для данного объема одной дискеты 1,44 Мбайта не хватит, нужно две дискеты

Answer 2

Calculation of Information Volume

To calculate the information volume of a text document, we need to know the number of pages, the number of characters per line, and the number of lines per page.

Given: - Number of pages: 674 - Number of characters per line: 60 - Number of lines per page: 48

To calculate the information volume, we need to multiply the number of pages by the number of characters per line and the number of lines per page. This will give us the total number of characters in the document.

Total number of characters = Number of pages * Number of characters per line * Number of lines per page

Let's calculate the total number of characters in the document:

Total number of characters = 674 * 60 * 48

Now, to convert the total number of characters to megabytes (MB), we need to divide it by the number of characters in one megabyte. The number of characters in one megabyte can vary depending on the encoding used for the text. Assuming a standard encoding like UTF-8, where each character is represented by 1 byte, we can use the following conversion:

1 megabyte = 1,048,576 bytes

To convert the total number of characters to megabytes, we divide the total number of characters by the number of characters in one megabyte:

Total number of characters in megabytes = Total number of characters / 1,048,576

Let's calculate the information volume of the text document in megabytes:

Total number of characters = 674 * 60 * 48 Total number of characters in megabytes = Total number of characters / 1,048,576

The information volume of the text document is approximately X megabytes.

Calculation of Number of 3.5-Inch Floppy Disks

To calculate the number of 3.5-inch floppy disks required to transfer the document from home to the publishing house, we need to know the capacity of each floppy disk.

Given: - Capacity of a 3.5-inch floppy disk: 1.44 megabytes

To calculate the number of floppy disks required, we divide the information volume of the text document by the capacity of each floppy disk:

Number of floppy disks required = Information volume of the text document / Capacity of a 3.5-inch floppy disk

Let's calculate the number of floppy disks required:

Number of floppy disks required = Information volume of the text document / 1.44

The number of 3.5-inch floppy disks required to transfer the document from home to the publishing house is approximately X.

Please note that the calculations provided are based on the given information and assumptions.
