What type of Internet usage is typically associated with requiring the most bandwidth?

Streaming video is typically associated with requiring the most bandwidth due to the large amount of data transmitted in a continuous flow to deliver high-quality visuals and audio. When streaming video, particularly in high definition or ultra-high definition, significant amounts of data must be downloaded in real-time to prevent buffering and ensure a smooth viewing experience.

In contrast, activities such as online shopping, sending newsletters, and web browsing generally consume much less bandwidth. Online shopping mainly involves loading web pages and transferring relatively small amounts of data, while sending newsletters typically involves transmitting text and images rather than large video files. Web browsing also usually requires less bandwidth as it involves accessing and viewing text-heavy pages that do not require the continuous flow of data that streaming video necessitates. Thus, the considerable data requirements for streaming video make it the activity that demands the most bandwidth among the given options.
