- From the users' point of view, it is called "concurrent
- access". For programmers and designers, they use "concurrent control"
- and "concurrent programming". CD-ROM player will definitely affect
- the speed, but other factors like central processor, application
- software, et al., will play important roles . Poorly programmed
- application software will cause problems to your cd-rom lan.
