It can make users do experiments easily, observe experimentphenomena and results through the remote terminal. Consequently, users can get final results toverify relative theory. The article analyses the features of virtual lab systems. A real virtual labsystem named 'Multimedia Virtual Lab for Digital Circuit Logic Design (MVLDCLD)' which has beendeveloped by the authors and their group is also presented.展开更多

文摘A virtual lab system is the simulation of real devices and experiments usingcomputer and network technology. It can make users do experiments easily, observe experimentphenomena and results through the remote terminal. Consequently, users can get final results toverify relative theory. The article analyses the features of virtual lab systems.
