Ingenious use of channel function to solve the problem of poisoning multimedia teacher computers
As a new classroom teaching method, multimedia classrooms have been widely used in schools. Teachers can use multimedia teacher computers to centrally process and display resources such as video, audio, images, animation, graphics and text, so as to achieve good interactive classroom teaching effects.
Multimedia classrooms are often distributed in one building or even several buildings, and each classroom has only one computer, which is very scattered. How to maintain these computers is a big problem.
Currently, multimedia teacher computers generally only install one operating system, and use protection card products to protect the operating system. However, in order to facilitate the teaching teacher to save the PPT and other courseware materials needed for teaching, the multimedia teacher will also reserve an unprotected partition for the teaching teacher to use. However, this mode of operation poses huge security risks! This is because the materials required by teachers for class are generally carried through the U disk. If there is a virus on the U disk (commonly such as autorun.inf, copy.exe, host.exe, rose.exe, etc.), then on the multimedia teacher machine When used, it will infect unprotected partitions on the hard disk, thus forming a vicious circle of cross-infection between the U disk and the hard disk partition and the hard disk partition. In severe cases, it may even cause a series of problems such as loss of courseware, program destruction, and operating system failure. It not only seriously affects the normal order of teachers, but also brings 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 the above problems very well!
After installing the multimedia teacher computer's operating system and required software, the administrator sets all hard disk partitions to the protected state. Based on this, using the single-system multi-channel function, the administrator can create up to 200 channel environments. The operating system and software environment of each channel are the same as the real system, and the channel does not occupy any hard disk space. . The administrator can set any channel as the operating system environment normally used by the lecturer, and modify the restoration method to unprotected. In this way, the instructor can normally save courseware information and teaching operations on the channel. If the channel is infected or damaged by the virus, the administrator can call other channels to use it on a stand-alone or remotely, and delete the infected channel. It does not affect the normal teaching of the instructor, and it also eliminates the management and maintenance of the multimedia teacher machine of the administrator to the greatest extent.
In this way, using the single-system multi-channel function, while using multimedia classrooms to improve the teaching effect, it also reasonably avoids the series of problems caused by the infection of multimedia teacher computers and allows the multimedia teacher computers to operate steadily.
