high-bandwidth

The term is a modern technical compound built from established English words. "High" intensifies the capacity, while "bandwidth" itself is a metaphor from radio engineering, where "band" denotes a contiguous range of frequencies and "width" measures its size. Literally, it means "a great width of the frequency band." This concrete image of a wide pathway evolved into the abstract computing sense, denoting a communication channel's capacity to carry data, where greater width allows for faster, more voluminous transmission. The logic perfectly connects the physical analogy to its digital function.

Structure: high (great) + band (range) + width (measure) - high: From Old English hēah, meaning "tall, lofty, high in position or degree." In this compound, it functions as an intensifier meaning "great." - band: From Old Norse band, meaning "something that binds," later specialized in electronics to mean a range of frequencies. In this word, it refers to the range of frequencies used for signal transmission. - width: From Old English wīdu (related to wīd, "wide") + the noun-forming suffix -th, meaning "the measurement or extent of something from side to side." Here, it refers to the measure of the frequency range.
