Which term is used for embedded applications or systems that need to consider the worst-case scenario in design?
Pessimistic Systems
What is a key requirement for embedded systems operating in Real Time?
Not missing any deadlines for tasks or operations
Why is the unit cost very high during the introductory stage of a product like a cell phone?
Due to high investments and no returns at the product development phase
When does profit occur for a product according to the text?
When the total returns exceed the investment and operating cost
What is MTBF (Mean Time Between Failures) a measure of?
Frequency of failures in hours/weeks/months
How would you define 'Throughput' based on the text?
The rate of production or operation over a defined process in a specific time period
What characteristic defines a Real-Time system according to the text?
A system that adheres to strict timing behavior and responds within a known amount of time
What is Product life-cycle curve according to the text?
Graphical representation of unit cost, product sales, and profit over various stages from conception to disposal
What does the quality attribute 'response' measure in a system?
The quickness of the system
Why is fast response critical in an embedded system used in flight control applications?
