The advantage is that the CD is short and the damage is good. The disadvantage is that advanced skills books are very expensive.Compared with other quite sophisticated network attacks, DDOS attacks are not only the use of attack techniques, but also a competition of resources, including network bandwidth resources and server resources. Without sufficient resources, it is nonsense to talk about defending DDOS attacks. Therefore, at present, the defense against DDOS attacks mainly lies in hardware protection, and software protection has little effect.　　升学的压力和独立的个性会发生怎样的碰撞？懵懵懂懂的学生们如何一次次成长？含辛茹苦的家长又是如何喜上眉梢？师生们如何快乐工作，快乐学习？整部情景剧中不仅有涉及等课堂内外的师生互动场景，触动广大观众的校园情怀，遍布笑点泪点；更有当下话题热点，如艺考、自主招生等教育热点；另外还有父母亲子之间围绕学习与升学的酸甜苦辣小故事，情节新颖又富有想象力。
