All modern communication depends on manipulating and controlling signals within the electromagnetic spectrum. B    Bandwidth is a reference to the capacity of a network’s communications like that allow data to be moved between nodes. The range of frequencies necessary for an analogue voice signal, with a fixed telephone line quality (recognizable speaker), is 300 - 3400 Hz. The answer is related to how language evolves. However, broadly defined, bandwidth is the capacity of a network. It means that digital signals are directly transmitted over transmission line. So, the higher the capacity of the communication link, or pipe, the more data can flow through it per second. Reinforcement Learning Vs. Communication Bandwidth: Bandwidth as a Measure of Data Transfer Given the actual definition of bandwidth—i.e., the width of a band of frequencies—why is this term used to describe concepts like data transfer rates?
