公司实时任务和软实时任务之间的区别

实时任务通常分类为–硬和软，但在广泛的范围内，实时任务分类为：

1. 硬实时任务
2. 公司实时任务
3. 软实时任务

1.公司实时任务：
公司实时任务是与时限相关联的此类实时任务，任务需要在截止期限内产生结果。尽管公司实时任务与硬实时任务不同，因为一旦超过了截止期限且任务未完成，硬实时任务便会失败，但系统会发生故障，但是即使在截止期限过去之后，如果是公司实时任务，系统也会执行不失败。

例子：

1. Video conferencing
2. Satellite based tracking 

2.软实时任务：
软实时任务是这种类型的实时任务，它们也与时间限制相关联，但是在此时序约束未表示为绝对值。在软实时任务中，即使在截止日期之后，也不会认为结果不正确，也不会发生系统故障。

例子：

1. Web browsing
2. Railway Ticket Reservation

It needs to be completed within the deadline.	It also needs to be completed within deadline but not strictly.
The value of associated timing constraint is taken as absolute.	The value of associated timing constraint is taken as average value.
The utility of result becomes zero after the deadline.	The utility of result decreases after the deadline but it gradually becomes zero.
Result obtained after deadline is considered incorrect.	Result obtained after deadline is not incorrect.
