DataMining can be divided into three categories and six sub-items: Classification and Clustering belong to the Classification and segmentation class; Regression and Time-series belong to the prediction class; Association and Sequence belong to the Sequence rule class. Classification is calculated based on the values of some variables and then classified based on the results. (The calculation result is

vswitch supports network management, we can divide it into two categories: "Network Management" and "non-network management.
The job of a network-managed switch is to keep all network resources in a good state. Vswitch provides various network management methods, such as Console Based on the terminal control port, Web pages, and Telnet remote logon network. Therefore, the network administrator can perform local or remote real-time monitoring on the s
