D. response time minus the detection time
View Answer
Ans : D
Explanation: Latency is defined as the response time minus the detection time.
10. If a system doesn't have timing constraints, it is not real-time.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Every real-time system has a set of timing constraints that it has been designed to meet. If a system doesn't have timing constraints, it is not real-time.
