Buffer

1. When referring to memory, a buffer is temporary storage in memory used to temporarily store information while other information is being processed.
2. Online you may see buffering with online streaming videos and music before they play. This buffering is done to help keep the media file from stopping when it does start to play by downloading a portion of the file first.
