Application of channel function in multimedia computer room
With the development and popularization of computers and multimedia information technology, a classroom equipped with multimedia computers, LCD projectors, digital video display stands, central control systems, projection screens, audio equipment and other modern teaching equipment is used to form a multimedia classroom as a New classroom teaching methods have been widely used. Instructors in multimedia classrooms use multimedia computers to centrally process and display resources such as video, audio, images, animations, graphics, and text to achieve good interactive classroom teaching.
Generally, only one operating system is installed on the multimedia computer, and only office software, player software, animation software and other basic software required for teaching are installed. At the same time, an unprotected system partition is reserved for the teacher to save courseware information such as PPT. The PPT, video, audio and other materials required by teachers for class are generally carried through storage devices such as U disks, and U disk storage devices are one of the three main ways to spread the virus! At present, a significant problem in front of the multimedia classroom administrators is that the operating system installed on the multimedia computer often suffers from system poisoning and crashes due to U disk infection and local area network transmission. In serious cases, the system even appears. The collapse not only severely affected the normal order of teachers, but also brought a huge workload to the management and maintenance of multimedia classroom administrators.
Using the single-system multi-channel function of Wuhan Ohi Technology Co., Ltd. products can solve this problem well. After installing the multimedia computer operating system and required software, the administrator can create multiple channel environments based on this. The operating system environment and protected status of each channel are the same as the real system. In this way, the administrator can set a channel to be used normally every day. The teaching teacher ’s data storage and teaching demonstration are operated on the channel. If this channel If the system crashes due to virus infection or destruction, the administrator can remotely call the real operating system or other channels to use it, which does not affect the normal teaching of the instructor at the same time, and also eliminates the administrator ’s multimedia computer management and maintenance work.
In this way, while using the multimedia classroom to improve the teaching effect, we also reasonably avoid the multimedia computer "infecting a virus → spreading the virus in the local area network → operating system crashing → causing teaching accidents" and other chain problems, so that the multimedia classroom is always running stably.
