Balanced Transmission
Method of transmission by sending a signal to the form of electrical current to be transmitted through a conductor. The signal will then be returned by a different conductor.
Bandwidth
Transmission capacity of a network connection such as electronic communications, computers and computer bus channel. Commonly denoted by the bits per second or Hertz. If written in Hertz, then the number be greater than if written in bits per second. For example, when written in bits per second is 64 Kbps, which means it is 64 kilobits per second or 8 kilobytes per second. It is typically used to measure the speed of the Internet we're using. Note 1Bytes = 8 bits
