The research on classification ability is more in kindergartens and more in primary schools. Research by cognitive psychologists has found that children under 0-1 years old basically have no classification ability, and they mainly rely on individual perception.

The classification of children aged 3-5 is basically still based on external perceptible dimensions such as shape and color. For example, children in small classes in kindergartens are asked to classify red plastic balls, red apples and bananas.

However, it will be more difficult to prevent distributed SYN flooding attacks launched by attackers using the advantage of the number of hosts in the network. As shown in FIG. 3, these host groups can use direct attacks or further let each host use spoofing attacks.比什么都重视友情的高中生·片切友一
