What term describes the frequency spectrum required by communication networks?

The term that describes the frequency spectrum required by communication networks is bandwidth. Bandwidth refers to the range of frequencies within a given band that can be used for transmitting data or signals. It essentially measures how much data can be transferred in a given amount of time; a higher bandwidth indicates a greater capacity for transmitting information.

In the context of communication networks, bandwidth is crucial because it determines the speed and quality of the connection. When a network has more bandwidth available, it can handle more data transmissions simultaneously, which is essential for high-demand services like streaming video, online gaming, and large file transfers.

While frequency itself is a component of bandwidth, it does not encompass the entire concept. Megahertz is a unit of measurement often used to quantify frequency, but it doesn't define the range of that frequency spectrum as bandwidth does. Standing Wave Radio relates to a specific characteristic of radio wave transmission, which is not applicable in describing the overall capacity of communication networks. Thus, bandwidth is the appropriate term to capture the full essence of the frequency spectrum needed for effective communication in a network setting.
