RTOS Fundamentals Quiz

What is the main purpose of an RTOS?

• Managing databases

• Controlling real-time embedded systems

• Running desktop applications

• Editing multimedia files

Which of the following is NOT an example of a real-time application?

• Air traffic control

• Web browsing

• Missile control systems

• ABS in cars

In a hard real-time system, what happens if a deadline is missed?

• Nothing serious occurs

• The system tries to recover

• Catastrophic system failure

• The system slows down

Which of the following is a characteristic of a soft real-time system?

• Deadlines must always be met

• Missing a deadline can lead to system failure

• Occasional missed deadlines are acceptable

• Used only in mission-critical applications

What type of scheduling does an RTOS typically use?

• First-Come, First-Served

• Priority Scheduling

• Round Robin Scheduling

• Multilevel Queue Scheduling

Which of the following examples represents a hard RTOS system?

• Multimedia playback

• Web server response time

• Airbag deployment in cars

• Telecommunication switching

What is the key difference between a GPOS and an RTOS?

• GPOS is faster than RTOS

• GPOS can handle real-time applications

• RTOS guarantees response within a specified time

• RTOS cannot run on embedded systems

Which of the following is true about clock-driven scheduling in RTOS?

• Tasks are scheduled based on a time quantum

• Tasks are scheduled dynamically at runtime

• Schedule is computed at regular time intervals

• It is used when execution time is not known

In round-robin scheduling, how are tasks scheduled?

• Based on priority

• In a circular manner with equal time quantum

• Using a shortest job first approach

• Based on earliest deadline first

What does an interrupt cause in an RTOS system?

• Immediate termination of all processes

• Processor to execute a code that responds to the interrupt event

• Processor to ignore the event

• Task scheduling based on priority
