Rebuffering is a common issue encountered when streaming media content online. It refers to the temporary pause or interruption in the playback of a video or audio stream, typically caused by slow internet connection or network congestion.

When rebuffering occurs, the media player needs to pause and buffer additional content to ensure smooth playback. This buffering process allows the player to store a certain amount of data in advance, reducing the likelihood of interruptions during playback.

Rebuffering can be frustrating for users, as it disrupts the viewing experience. Factors such as low bandwidth, network congestion, or heavy internet traffic can contribute to rebuffering. To minimize rebuffering, it is advisable to have a stable and high-speed internet connection.

Content providers and streaming platforms employ various techniques to mitigate rebuffering, such as adaptive streaming, which adjusts the quality of the media based on the available bandwidth. Additionally, content delivery networks (CDNs) help distribute the load across multiple servers, reducing the chances of rebuffering.
