求翻译：（4）其中一对线专门发送数据，另一对线专门接收数据，这样的交换式全双工的实时工业以太网就消除了数据在网络上碰撞的问题，使Ethernet通讯的确实性和实时性又大大提高了一步。是什么意思？

(4) where a pair of lines dedicated to send data, and the other on-line dedicated to receiving data, such as real-time full-duplex switched Ethernet to the data on the network to eliminate the problem of collisions, so that the exact nature and Ethernet communications has greatly improved real-time

( 4) One of the on-line specialized send data, on the other hand, so that data on-line dedicated to receiving the switching full-duplex real-time industrial Ethernet to eliminate the data on the network, so that the problem of collisions Ethernet communications of certainty and real-time has greatly

(4) where a pair of lines specifically send data, another to receive data, such a switched full duplex real-time industrial Ethernet eliminates the data in the problem of collisions on the network so that certainty and real-time Ethernet communication and has greatly enhanced the step.

(4)A pair of lines specially send the data, another pair of lines specially receives the data, such exchange type all duplexing real-time industrial Ethernet dispel the question that the data collide in the network, really make Ethernet communicate really and the real-time character has been greatly
