1.shell 和 CPU 和kernel的关系是什麽呀??
2.Assume that there are three periodic events in a real-time system.
These three events occur with period 100,200,300 ms, respectively.
These three events require 50,50,100 ms of CPU time, respectively.
Show that this real-time system is not schedulable.
这题到底在问什麽?? 看不懂@@
3.stateful protocol 和 stateless protocol 各是什麽意思呀?
我有上网查了，但还是不太懂他们真正的分别...
