other network devices are physically damaged, the damaged network adapter will continuously send a large number of packets to the switch, many of which are invalid, A large number of useless data packets may cause information transmission delay and network congestion, resulting in broadcast storms and slow lan network speeds. This can be used as a replacement method to eliminate network device faults. The NIC, hub, and switch are the most prone devic

By default, IOS video players adopt a two-dimensional slide to control video advances and advances: Operation: press the slider and slide along the vertical direction. Based on the switching speed of the sliding distance, the slider moves forward and backward horizontally. after release, the video progress takes effect. Effect: the green line indicates the actual sliding distance of the hand, and the purple line in
