[問題] 一些計概的問題

[aquariusgirl (學，然後知不足)]

1.shell 和 CPU 和kernel的關係是什麼呀??


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.


 這題到底在問什麼?? 看不懂@@


3.stateful protocol 和 stateless protocol 各是什麼意思呀?

  我有上網查了，但還是不太懂他們真正的分別...
