在当今,网络概念已深入人心,计算机网络和数据通信已经成为大家关注的重点内容。只有具备数据交换能力的网才称得上是网络如何更为高效的完成数据通信,扩展网络规模就与数据交换技术密切相关,在通信系统底层硬件实现的信号传输的基础上,实现通信双方之间的数据交换,由此才能真正的完成一次通信过程。随着计算机技术的不断发展,计算机网络的规模越来越大,网络结构越来越复杂,数据交换技术也随之进步与发展。
In today’s world, the concept of network has gained popularity. Computer network and data communication have become the focus of everybody’s attention. Only with the ability of data exchange network can be said to be more efficient network to complete data communications, network expansion and data exchange technology is closely related to the communication system in the underlying hardware to achieve the basis of signal transmission, the two sides to achieve communication Between the data exchange, which can really complete a communication process. With the continuous development of computer technology, the scale of computer network is getting bigger and bigger, the network structure is more and more complicated, and the data exchange technology also advances and develops.
