The quality of the twisted line quality is one of the key factors that determine the width of the local area network. Some manufacturers are wrapped in the line pairs of 3 or 4 UTPs in the five types of UTP cables. It is difficult to distinguish this counterfeit method for ordinary users.

This so -called "five types of UTP" cannot reach the data transmission rate of 100Mbps, with a maximum of 10Mbps or 16Mbps. A simple way of identifying is to connect two 100Mbps devices (network cards to network cards or network cards to HUB) with a twisted line, and use Windows95/98 Monitor detection tools to monitor its data transmission rate.

The method is: ① Select the "Start → Program → Annex → System Tools → System Monitor", which will appear a "System Monitor" window. If there is no "system monitor" tool in "System Tools", it can be established through "My Computer → Add/Delete Program → Windows Installation Program → System Tools → System Monitor".

② Set monitoring objects in the "System Monitor" window. Select the "Added Project" option in the "Edit" menu, select "Microsoft Network Server" or "Microsoft Network Customer" in the "Category" list of the dialog box that appears In a dialog box, select "Writing by bytes/seconds" or "Read the number of bytes/seconds".

As for the selection of "Microsoft Network Server" or "Microsoft Network Customer", it is "the number of bytes written in the write" or "the number of bytes of the read". The data should be equal to the data received by another node.

③ Set the output method of test data. The system provides three output methods: line diagram, bar chart, and number chart, which can be selected by the button in the window toolbar. ④ Test.

The most effective way is to copy a large number of files from the workstation where the server tests (for the accuracy of the test, the copy must be enough). Generally speaking, the displayed value of the display is above 4m/s, which is basically sure that the five types of network cables (the peak values that can be achieved by the three types of 3 lines are about 2.5m/s).
