Techopedia explains Burst
Most data bursts are temporary and unsustainable, and generally, data is sent at faster than normal transfer rates that are not long term and only under special conditions.
Data bursts are created in various ways. An example is when a device is allowed to seize control of a data bus, while other devices are not permitted to interrupt the operation. Another example occurs before a request, when memory content is automatically fetched in RAM.
