Answer: B) Band width Explanation: The path that data takes from source to destination is called a Channel. A channel is a communication medium. A channel has a certain capacity for transmitting information.    The "capacity" of a channel is the theoretical upper-limit to the bit rate over a given channel that will result in negligible errors. Channel capacity is often measured by its Bandwidth in Hz or its data rate in bits per second.
