In order to realize the construction of smart campus application system and accelerate the process of educational informatization, more and more schools begin to build their own modern teaching rooms. Some of these computer rooms are deployed by traditional desktop computers, which we call traditional computer rooms, and some are deployed by cloud terminals and servers, which we call cloud computer rooms. What is the difference between the cloud computer room built by the cloud terminal and the traditional computer room being used?

First of all, it works differently. The cloud computer room is mainly composed of server and cloud terminal. The cloud terminal is hung behind the monitor, and the data is not stored and calculated locally. All data and calculations are used by calling the server's data. The traditional computer room is mainly composed of desktops, and the performance of desktops mainly depends on the configuration of the host.

Secondly, the use cost is different. A 45-person cloud computer room only needs one server and 45 cloud terminals. The average power consumption of a server+Yulong cloud terminal will not exceed 30W, while the average power consumption of desktop computers used in traditional computer rooms is 200W, which means that an ordinary traditional computer room consumes more power 170W than a cloud computer room using cloud terminals. According to statistics, compared with traditional computer rooms, cloud computer rooms can save 95% of electricity bills every year.

Third, the maintenance difficulty is different. The maintenance of cloud computer room built with cloud terminal is like this. If it's a system problem, the teacher only needs to maintain it on the server, but if it's a cloud terminal hardware problem, it's simpler, just get a good replacement. The maintenance of traditional computer rooms is like this. Both system problems and host hardware problems need local maintenance. Just reinstall the system problem. If it's a hardware problem, you need to check every piece of hardware to see what's wrong.

Fourth, the degree of control is different. For schools, teachers can control all cloud terminals through teachers' computers, release teaching desktops and exam contents to all cloud terminals, and prohibit access to peripherals such as USB flash drives. However, because the traditional computer room is used for technology and storage, teachers can't control every computer in real time through their computers.

From the comparison, we can see that the cloud computer room built with cloud terminal will be very different from the traditional computer room built with desktop computer.
