Question

Скорость передачи данных через ADSL-соединение равна 256 000 бит\с. Через данное соединение передают файл размером 3.5 Мбайт. Определите время передачи файла в секундах.

Answer 1

256000 bit/s = 0,032 MB/s
3,5 : 0,032 ≈ 110с

Answer 2

Calculating Data Transmission Time via ADSL Connection

To calculate the time it takes to transmit a file through an ADSL connection, we can use the formula:

Time (in seconds) = File Size (in bits) / Transfer Rate (in bits per second)

Given: - Transfer rate through ADSL connection: 256,000 bits per second - File size: 3.5 megabytes (MB)

First, we need to convert the file size from megabytes to bits: 1 byte = 8 bits 1 kilobyte (KB) = 1024 bytes 1 megabyte (MB) = 1024 kilobytes

So, 3.5 MB = 3.5 * 1024 * 1024 * 8 bits

Now, we can calculate the time it takes to transmit the file.

Calculation

``` File Size (in bits) = 3.5 * 1024 * 1024 * 8 Transfer Rate = 256,000 bits per second

Time = File Size / Transfer Rate ```

Result

After performing the calculation, the time it takes to transmit the file through the ADSL connection is approximately 92.8 seconds.

This calculation is based on the provided transfer rate of 256,000 bits per second for the ADSL connection
