Question

Скорость передачи данных adsl соединение равна 128 000 бит/с через данное соединение передают файл размером 625 Кбайт определите время передачи файла в секундах

Answer 1

128000 бит сек / 8 / 1024 =15,625 кбайт сек
625 кбайт / 15,625 кбайт сек = 40 сек

Answer 2

Calculation of File Transfer Time

To calculate the time it takes to transfer a file over an ADSL connection with a data transfer speed of 128,000 bits per second, we need to convert the file size from kilobytes to bits.

Given: - Data transfer speed: 128,000 bits per second - File size: 625 kilobytes

To convert the file size from kilobytes to bits, we multiply it by 8 (since there are 8 bits in a byte): 625 kilobytes * 8 = 5,000 kilobits

Now, we can calculate the time it takes to transfer the file using the formula:

Time = File Size / Data Transfer Speed

Substituting the values: Time = 5,000 kilobits / 128,000 bits per second

Calculating the result: Time = 0.0390625 seconds

Therefore, it would take approximately 0.0390625 seconds to transfer a file with a size of 625 kilobytes over an ADSL connection with a data transfer speed of 128,000 bits per second.

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