The term "bandwidth" refers to the maximum rate of data transfer across a network connection or the capacity of a communication channel. In a more technical sense, it's the range of frequencies used for transmitting data. Higher bandwidth means more data can be transmitted at once, making connections faster and more efficient.
The word "bandwidth" is derived from the combination of "band," referring to a range of frequencies or a specific interval, and "width," signifying the extent or measurement of that range. It is rooted in the fields of telecommunications and signal processing.
