The data transfer rate over ADSL connections is 64000 bps. Determine the time it takes to transfer a 64K

The data transfer rate over ADSL connections is 64000 bps. Determine the time it takes to transfer a 64K file over this connection.

First, let’s convert the file transfer rate in bits to kilobytes. Based on the fact that there are eight bits in one byte, and 1024 bytes in one kilobyte:

64000 bits = 64000/8 bytes = 64000/8/1024 kilobytes = 7.8125 kilobytes per second.

The information stream is capable of transmitting 7.8125 kilobytes per second per second. Let’s divide the size of the information to be transferred by the bandwidth. This will be the solution to the problem:

64 / 7.8125 – needs at least 9 seconds.
