Bandwidth Definition: Available range of frequencies for transmission on a single communications line. The measurement determining how many bits of information can be transmitted per second on a given network.1The greater the bandwidth, the greater the speed of transmission of data.In ALS Scan v Digital Services, Justice Niemeyer of the United States Court of Appeals adopted these words:"Bandwidth ... has been explained by the following analogy: If you think of the Internet as the Information Superhighway, then think of bandwidth as how many lanes of traffic it can handle. Bandwidth describes how much information can be sent over a connection at one time."REFERENCES:ALS Scan, Inc. v.
