Bandwidth is the amount of data that can be sent over an internet connection or cable within a given time.
A higher bandwidth allows smoother streaming of high-quality video, such as 4K or 8K, without buffering.
For TV and streaming, bandwidth determines how quickly a movie, live sports, or a game can load and play without interruptions.
