Question

Скорость передачи данных через ADSL - соединение равна 512000 бит\с. Через это соединение передают файл размером 1500 килобайт. Определите время передачи файла в секундах.

Answer 1

Файл размером 1500 килобайт при входящей/исходящей скорости 512 Кб/сек будет загружаться 23 секунды

Answer 2

Calculation of File Transfer Time

To determine the time it takes to transfer a file over an ADSL connection with a speed of 512,000 bits per second, we need to calculate the transfer time in seconds.

Given: - Connection speed: 512,000 bits per second - File size: 1500 kilobytes

To calculate the transfer time, we can use the formula:

Transfer Time = File Size / Connection Speed

Converting the file size from kilobytes to bits: - 1 kilobyte = 1024 bytes - 1 byte = 8 bits

Therefore, the file size in bits is: - 1500 kilobytes * 1024 bytes/kilobyte * 8 bits/byte = 12,288,000 bits

Substituting the values into the formula: Transfer Time = 12,288,000 bits / 512,000 bits per second

Simplifying the calculation: Transfer Time = 24 seconds

Therefore, it would take approximately 24 seconds to transfer a file with a size of 1500 kilobytes over an ADSL connection with a speed of 512,000 bits per second.

Please note that the calculation assumes ideal conditions and does not account for any overhead or network congestion that may affect the actual transfer time.
