The network connection components are the cable, which determine the speed of the LAN. Cables have a speed measure in bps (bits per second), which indicates how many bits can flow through the cable in one second.

To find out how much time it takes to transfer a file with a size in bytes, divide the Connection speed in bps to 8 byte rate per second to find out and then divide the file size by the speed of the number of seconds to see it take place for the file transfer. In order to transmit, for example, a 600 MB file via a Fast Ethernet connection to the speed of 12.5 MB per second out (12,500,000 bytes per second) and then divide 600 MB (or 600 million bytes) of 12.5 (or 12.5 million) to find out the time of 48 seconds.
