Question

Скорость передачи данных по некоторому каналу связи равна 64000 бит/с. Сколько секунд будет длиться передача по этому каналу файла размером 125 Кбайт?

Answer 1

125 Кбайт = 1000000 бит
1000000\64000=15.6 сек

Answer 2

Calculating Data Transmission Time

To calculate the time it takes to transmit a file over a given channel, we can use the formula:

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

First, we need to convert the file size from kilobytes to bits: 125 kilobytes = 125 * 8 * 1024 bits = 1,024,000 bits

Now, we can use the given data transmission rate: Data Transmission Rate = 64,000 bits per second

Using the formula: Time = 1,024,000 bits / 64,000 bits per second = 16 seconds

So, the transmission of a file with a size of 125 kilobytes over a channel with a data transmission rate of 64,000 bits per second will take 16 seconds.
