The old computer lab are with conventional desktop pc. Its management and maintenance usually is handled by IT administrators.But this kind of old computer management mode can not meet current student's teaching requirements. Sometimes, it limits teaching process. The following are disadvantages of using conventional desktop pc.

But now, we would like to introduce you a zero client solution for global computer labs. The solution not only can solve above mentioned questions, but it’s very competitive.The solution consist of 4 aspects: server, zero client box, VNOPN software, and a general pc.30 users deployments are as follows: Prepare ONE server, ONE general pc, ONE switch with gigabit Ethernet, VNOPN software, 30pcs for each items(zero clients, network cable with gigabit Ethernet, monitors, keyboards, mouses) First, make zero clients connect to monitor and other necessary peripherals. Second install “Hserver”program on server. Then install both “Hmanager”and “Hteacher”software on general pc. Finally, connect to start. When connecting, users should activate server and make sure all device are in the same network segment.

Process of deploying a computer lab with 60 students almost the same with above one. One thing different is that user need to add ONE more server. One server connect 30 zero clients. Two server can connect 60 zero clients. So user can configure and control two servers on Hmanager program.

Before class, teacher should deploy working environment first on Hmanager. Firstly, teacher should create desktop for partial or all terminals. Then choose partial or all terminals(Ctrl+A), make them to login server by right-click on mouse. If there any seat space limits, teacher can set seat NO. for students according to real seat space. After finishing, then teacher should close Hmanager program and run Hteacher program to start class.

When the lesson begins, the teacher can with one-key broadcast his desktop to all students, which enable every student to see clearly the teaching contents and operating steps. This assure high teaching learning effect. Even when students have independent learning ability, the teacher can continue to monitor all operating behaviors. It greatly simplifies multi-user management. The teacher can send the session to the absent-minded student. If the student doesn’t correct their behavior, the teacher can force to control of their terminals. When students want to ask any question, they can directly click hand up button and interact with the teacher. Students using U disks may unintentionally infect the computers. To avoid this problem, the teacher can set the students’ USB peripheral permissions. To check the learning result after class, the teacher can send e-papers for a quiz. And better prepare lessons according to students’ testing result. After class, the teacher can with one key to turn off students’ terminals but also make a whole-class check and summarize students’ operation behavior in class.
