局域网中各终端设备的数据传输速度不但取决于硬件设施的性能,而且与软件的合理配套和使用有着密切的关系。从硬件和软件两方面入手分析可以有效地优化一个局域网,使其能够更好地发挥作用。随着网络硬件的不断发展,网络中所用的交换机或网卡已经能够提供较大带宽。但在一个局域网内部,即使使用的网卡或交换机拥有较大带宽,还是会经常出现打不开网页或无法连通服务器的情况。特别是在一些设备档次参差不齐的网络中,这就涉及 The data transmission speed of each terminal device in the LAN not only depends on the performance of the hardware facilities, but also has a close relationship with the reasonable supporting and using of the software. Starting from both hardware and software analysis can effectively optimize a local area network so that it can play a better role. As network hardware continues to evolve, the switches or network cards used in the network have been able to provide greater bandwidth. However, within a local area network, even if the use of network cards or switches have a larger bandwidth, or often will not open the web page or unable to connect to the server. This is especially relevant in networks with varying levels of equipment
