(The shortcomings of network equipment and equipment cause the network speed to slow down. If the computer's network card or other network equipment is physically damaged, the damaged network card will continue to send many data packets to the switch, many of which are invalid, and many useless data packets will constitute information transmission delays, resulting in network delays. Blockage, which then causes broadcast storms, slows down the speed of the local area network. This can be a replacement method to clean up the shortcomings of network equipment.)
