It launches a space for new generation internal application,due to its supporting the complicated service efficiently and useable resource in the Internet. This paper sums up theresults and applications instance in the grid computing in the world during recent years ,and then analyzes emphaticallythe system architecture ,components ,working principle in the grid computing and some typical grid systems ,and thendiscusses the problems of the large scale science computing and network service in grid computing in China,and alsopoints out the future trends.展开更多

文摘On the basis of the result of a survey, the paper analyzes several ubiquitous drawbacks of existing distance education system, points out developing direction and user expectation of future distance education system. Sequentially, based on the analysis, we propose several related key research issues in the field of computer science and technology, which we think is the object researchers should put energy into.
