What is the primary focus of resource analysis in real time embedded systems?

• Processing and scheduling

• Memory allocation

• Input and output management

• Network security

What does a thread context switch involve?

• Increasing CPU clock speed

• Reducing memory usage

• Executing multiple threads simultaneously

• Saving the state of a running thread

Which of the following is NOT a parameter important for real time systems?

• Speed

• Efficiency

• Service frequency

• User interface design

What type of memory has the fastest access time?

• Level 2 cache

• Main memory

• Level 1 cache

• Nonvolatile memory

What is the consequence of a late response in hard real time systems?

• It is acceptable as long as it is within limits

• It can lead to negative utility

• It has no impact on the system

• It improves system performance

In the context of real time systems, what does 'I/O bound' refer to?

• Memory access issues

• Network delays

• Excessive I/O latency

• Insufficient CPU cycles

What is the main characteristic of soft real time systems?

• They require high reliability

• They are always deterministic

• They allow for some degree of lateness

• They cannot miss deadlines

Which scheduling policy assigns the highest priority to the service with the shortest deadline?

• Earliest Deadline First

• Least Laxity First

• Rate Monotonic

• Fixed Priority

What does the term 'interference' refer to in fixed priority systems?

• The time taken to execute a service

• The scheduling of tasks

• Preemption of a task before completion

• The total number of services in the system

What is the purpose of feasibility tests in real time systems?

• To analyze network performance

• To ensure that deadlines will not be missed

• To determine the maximum execution time

• To optimize memory usage
