cluster to provide consistent data services, naturally, it will be replicated across all machines. Benefits of data replication:1, fault tolerance: A node error, not to let the whole system stop working, other nodes can take over its work;2, improve the system expansion capacity: the load distributed to multiple nodes, or to increase the number of nodes to improve the system load capacity;3, Improve performance: Let the client local access to the nea
one driver not properly installed or working
Check the method is my computer right----management----Device Manager below to see if there is a yellow exclamation point, then your driver does not work properly. If this happens, reinstall the driver, and you can use the master driver upgrade to install the driver.

Failure Analysis: The general computer appears abnormal the first case of the idea is the virus infection invasion, this can not be ignored. The second is that the computer itself is set up incorrectly or the system files are lost and the registry is modified.
Workaround: First, hold down the Ctrl+alt+del key to open Task Manager, after opening in the Task Manager's main interface click on "File-New task", will pop up a new task to create a window, and then enter the window "Explorer.exe", and

There are many things worth learning about switched Ethernet. Here we mainly introduce the working principle and advantages of switched Ethernet. Ethernet SWITCH, which is also translated as a SWITCH or a SWITCH-type hub. Let's first review the development process of LAN.
The combination of computer technology and communication technology has promoted the rapid development of local computer networks. From the appearance of ALOHA at the end of to the a
transmission is reduced, and the efficiency of the entire network is also improved! People have found that bridges are really a good thing. With the development of hardware, there are four link layer devices with eight ports. This is a switch, because vswitches can make the network more secure (data is not easily listened to, because data is no longer broadcast. Note: It's just not easy, but you can still do it ), higher network efficiency (or because data is no longer broadcast !), Switches gr
