Multimedia network classroom, an integration of multimedia technology and network technology, is a modern teaching system. However, there exist some problems in the use of hard disk recovery card for computer protection. Diskless network means that no disk is installed in the workstation which automatically downloads the operating system from the server when the workstation is started by the card. Since the operating system and data are stored on the server, the management and maintenance of the network classroom is conducted on the server, which improves the speed of operation, reduces the cost and maintenance workload. Because of the application of diskless technology in multimedia network classrooms, multimedia software is simply installed in all computers from the server. With the control of the server and teacher' s computer, the multimedia teaching can be enriched, and the remote monitoring of students' computers is enhanced.%多媒体网络教室是集成多媒体技术与网络技术的现代教学系统,传统的多媒体教室采用硬盘还原卡保护计算机系统和硬盘数据,但实际应用中仍存在一些问题.无盘网络就是网络上的工作站没有安装硬盘,无盘工作站通过网卡启动后,自动从服务器下载操作系统.由于操作系统和数据都集中存储于服务器,整个网络教室的管理和维护只需在服务器上进行,提高了网络方式下的启动和运行速度,降低了硬件成本,减少了维护和更新的工作量.无盘网络技术应用于多媒体网络教室,多媒体软件通过服务器安装到全网络计算机,通过服务器管理端和教师机主控端的配合使用,丰富了多媒体网络教学的功能,增强了对学生机的远程监控和管理.
