  • Juan Guerrero thinks this is interesting:

When considering that these pulses of light or electrons are merely signals that when interpreted in groups comprise a frame of data, the capacity of a network medium can be measured in some number of bytes. This capacity value can be determined by multiplying the one-way latency of the network link with the maximum transmission rate in bytes and is called the bandwidth delay product (BDP). Note that the transmission rate must be first converted to bytes if initially represented in bits per second (simply divide the bits per second by eight to arrive at bytes).
