Packet burst broadband is a type of internet connection that allows you to get more speed for short periods of time. It works by sending lots of information (called packets) all at the same time in a 'burst'. This means you can get a lot of data very quickly, which will make your internet connection faster. However, when the burst ends, your connection will go back to normal speed. So, it's a good way to get a temporary boost if you need to do something that requires a lot of data in a short amount of time (like streaming a movie, playing an online game, or downloading big files).
