网络传输

网络传输是指用一系列的线路(光纤,双绞线等)经过电路的调整变化依据网络传输协议来进行通信的过程。其中网络传输需要介质,也就是网络中发送方与接收方之间的物理通路,它对网络的数据通信具有一定的影响。常用的传输介质有:双绞线、同轴电缆、光纤、无线传输媒介。网络协议即网络中(包括互联网)传递、管理信息的一些规范。如同人与人之间相互交流是需要遵循一定的规矩一样,计算机之间的相互通信需要共同遵守一定的规则,这些规则就称为网络协议。网络协议通常被分为几个层次,通信双方只有在共同的层次间才能相互联系。

I strongly believe that understanding is more important than love, especially when it comes to parenting and intimate relationships. As a psychologist for more than twenty years I can tell you that I have never had an adult looking back at her childhood and complaining that her parents were too understanding. And similarly, I have met many divorced people who still love each other but yet they never really understood each other. The painful reality is that love is just not enough. I"ll admit that there are people who I love and who I still need to better understand. I hope I"ll continue my work to understand them. The willingness to understand is very important. It is not always easy, but healthy love is strengthened by the willingness to understand. Love without understanding will wilt like flowers without water. Our egos are what seem to get in the way of understanding those who we love and care about. Often it is our need to be right that makes what others think and feel so wrong for us. I have certainly been quite guilty of this in some of my relationships. As I have written repeatedly in my books, empathy, is truly the emotional glue that holds all close relationships together. Empathy allows us to slow down and try to walk in the shoes of those we love. The deeper our empathy, the deeper—and healthier—our love. Not all relationships are meant to be. Yet all relationships that are meant to flourish in a healthy way, must stress understanding just as much, if not more, than love.Which of the following statements is true according to the passage
