以资源共享为特点的计算机通信网络,对提高劳动生产率、改善企业管理、发展国民经济,起着巨大的推动作用。在近几年推出的计算机通信网络当中,王安网络系统,把340MHz 的带宽分成若干独立的“波段”,利用宽带同轴电缆,进行频分多路信息传输。这种多功能、多通道、多用户的通信网络,号称“信息流的自由之路”。某些性能大大超过了使用基带同轴电缆技术的高档总线型 Ethernet 网络及其它网络。 Computer communication networks characterized by resource sharing play a huge role in promoting labor productivity, improving enterprise management and developing the national economy. Among the computer communication networks launched in recent years, Wang’s network system divides the bandwidth of 340 MHz into several independent “bands” and uses broadband coaxial cable to carry out frequency division multiple information transmission. This versatile, multi-channel, multi-user communication network, known as “the freedom of information flow.” Some of the properties outperform high-end bus Ethernet networks and other networks that use baseband coaxial cable technology.
