1 00:00:04,220 --> 00:00:07,840 The previous review will discuss the classification system. 2 00:00:08,380 --> 00:00:17,630 No system is the system and a system in which some specific work has to be done in this specific time 3 00:00:17,630 --> 00:00:20,300 period are called the time system. 4 00:00:20,330 --> 00:00:24,960 Is that in the realtime system we perform the task on a given day. 5 00:00:25,760 --> 00:00:31,700 The year time and belief system are classified into two types, such as operating system and harvill 6 00:00:31,910 --> 00:00:32,360 system. 7 00:00:32,840 --> 00:00:39,770 Now we discussed the software and Hamilton system in the software time systems. 8 00:00:40,090 --> 00:00:41,600 The tasks should be. 9 00:00:42,820 --> 00:00:51,010 Then in that 10 minute or one second, yeah, nine minute, 15 second, but in hard times system, the 10 00:00:51,030 --> 00:00:53,320 tasks could be done in 10 minutes. 11 00:00:54,100 --> 00:00:56,280 So time constraints are limited in that. 12 00:00:56,280 --> 00:00:57,430 How do you then system? 13 00:00:57,700 --> 00:01:02,590 Now we discuss a jumble of the ideal time and SoftLayer time system. 14 00:01:03,960 --> 00:01:10,180 A system in which work has to be done in a specific time period are called hard reality system. 15 00:01:10,390 --> 00:01:18,900 The example of the ideal time system, a missile with a tracking system and set an example is the aircraft 16 00:01:19,290 --> 00:01:23,540 in these two examples that time is the most important part. 17 00:01:24,240 --> 00:01:31,110 And the example of this operating system is that DVD player in the DVD player within the city. 18 00:01:31,350 --> 00:01:39,810 If we execute the code and education will be some take some delay, then it is not some matter. 19 00:01:39,960 --> 00:01:43,710 But in the aircraft and missile, that time is matter. 20 00:01:43,950 --> 00:01:47,340 The region importance of one or two systems. 21 00:01:47,520 --> 00:01:52,680 So in the aircraft and missile, we use the hardware time systems.
