Level 2 is calculated only on the basis of Level 15.9 Diseases and injuries of the central nervous system are unqualified.In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.For example, explain why the above points should be considered. If the event is passed to a View without child views, then the view's onTouchEvent () will be called back. We can decide whether to consume the event by overriding the return value of onTouchEvent (). If this event is down and onTouchEvent () returns false and does not consume it, then the events after the event sequence will no longer be distributed to this View. If the down event is consumed, then the subsequent events will continue to be distributed to this View. At this time, if a move event of the subsequent event is not consumed, then the events after this move event will still be distributed to this View.就听前边两人边走边说话。
