Bandwidth refers to the maximum amount of data that can be transmitted over a network in a given amount of time, usually measured in bits per second (bps). Think of it like a highway: the wider the road, the more cars (or data) can travel at once. If a network has high bandwidth, it can handle many users or large files simultaneously without slowing down. When you stream a video or download a file, you rely on the bandwidth of your internet connection. If the bandwidth is low, you might experience buffering or slow downloads. In contrast, high bandwidth allows for smooth streaming and quick file transfers, enhancing your overall online experience.
