Question

СРОЧНОО!!! 1. Книга, набранная на компьютере, состоит из 128 страниц, на каждой странице 32 строки, в каждой строке 64 символа. На компьютере ие- пользуется 256-символьный алфавит. Определите пропускную способ- ность устройства, передающего информационный объем данной книги за 2 минуты 8 секунд.​

Answer 1

Дано:

V = 128 страниц * 32 строки * 64 символа * i

N = 256 символов

t = 2мин. 8 с.

Найти:

q - ?

Решение:

V = 128 * 32 * 64 * i = 262 144 * i (символов)

N = $2^{i}$ ⇒ i = 8 бит = 1 байт

V = 262 144 * 1 = 262 144 байт = 256КБ

q = V/t

t = 128 с.

q = 256КБ / 128с. = 2Кбит/с

Ответ: 2Кбит/с

Answer 2

Calculation of the Information Volume

To determine the information volume of the given book, we need to calculate the total number of characters in the book.

Given: - Number of pages: 128 - Number of lines per page: 32 - Number of characters per line: 64

To calculate the total number of characters in the book, we can multiply the number of pages by the number of lines per page and the number of characters per line:

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

Total number of characters = 128 * 32 * 64

Total number of characters = 262,144

Therefore, the book consists of 262,144 characters.

Calculation of the Transmission Rate

To calculate the transmission rate, we need to determine the time it takes to transmit the entire book.

Given: - Time: 2 minutes 8 seconds

To calculate the total time in seconds, we can convert the minutes to seconds and add it to the given seconds:

Total time in seconds = (2 minutes * 60 seconds/minute) + 8 seconds

Total time in seconds = 120 seconds + 8 seconds

Total time in seconds = 128 seconds

To calculate the transmission rate, we can divide the total number of characters by the total time in seconds:

Transmission rate = Total number of characters / Total time in seconds

Transmission rate = 262,144 characters / 128 seconds

Transmission rate ≈ 2,048 characters/second

Therefore, the device transmitting the information volume of the given book can achieve a transmission rate of approximately 2,048 characters per second.
