First, the design content Design a process management simulation system that allows n processes to run concurrently. The system includes simple process control, synchronization and communication mechanism, and its process scheduling algorithm can be arbitrarily selected (priority scheduling, time slice rotation, one of the short process priorities). Each process is represented by a PCB and its contents are set according to the specific situation. There is a certain synchronization relationship b

WPS Demo set up a dual-screen playback method Dual-screen playback is divided into two modes: one is extended mode, that is, the audience can not see the operating interface, only to see the content of the display playback view. The other is cloning mode, where the audience sees the same operating interface as the speaker. However, it is more recommended that you use the extended interface, in which the Speaker view is provided, and all the tools req

box that pops up later. See Figure 3: Third, let the background music start and end all listen to us from which slide the background music starts, we can control it by inserting a background music on this slide. So how do we control background music to stop on a slide? One possible way to do this is to randomly insert a background music on a slide that needs to stop the background music, and then turn the background music volume to 0 or select mute directly, as described earlier

very useful feature of the WPS demo, which can be used to simulate the path's irregular graphics route and display it as a custom path.
