The bandwidth of a channel is the frequency range over which it can transmit a signal with reasonable fidelity. What are different types of communication media? Bandwidth, in electronics, the range of frequencies occupied by a modulated radio-frequency signal, usually given in hertz (cycles per second) or as a percentage of the radio frequency. What is it? U    Reinforcement Learning Vs. Bandwidth describes the maximum data transfer rate of a network or Internet connection. Rate is the number of transmitted bits per time unit, usually seconds, so it's measured in bit/second. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps, (125 megabytes per second). The definition comes from the field of engineering where bandwidth represents the distance between the highest and lowest signals on a communication channel (band). It is also called bounded media. #    Bandwidth is measured in bits, megabits, or gigabits per second. It transmits only one signal at a time. While bandwidth is officially measured as a frequency (Hz), it … It transmits several streams of data at the same time using FDM (Frequency division Multiplexing) technique. Bandwidth can be compared to the amount of water that can flow through a water pipe. The term bandwidth sometimes defines the net bit rate 'peak bit rate', 'information rate,' or physical layer 'useful bit rate', channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system.
