Embedded Systems Quiz

Which best describes the term embedded in embedded systems?

• Combining unrelated tasks into one system

• Attaching a system to the internet for updates

• Integrating hardware and software into another system for a purpose

• Using a general-purpose computer for multiple tasks

Which scenario illustrates the single-function nature of embedded systems?

• A smartphone that runs multiple apps simultaneously

• A laptop used for gaming, programming, and browsing

• A fitness tracker that only monitors heart rate and steps

• A desktop that can run any compatible software

Which of the following best explains why embedded systems are 'tightly constrained'?

• They rely on complex multi-core processors

• They operate with ample memory and storage

• They are designed with resource limitations to optimize performance

• They must connect to a network to share resources

Which is a practical example of a real-time embedded system?

• A photo editing app on a PC

• An airbag deployment system in a car crash

• A smartwatch calendar reminder

• A wireless printer

Which feature distinguishes a microcontroller from a microprocessor in embedded systems?

• Microcontrollers require external RAM and ROM

• Microcontrollers integrate CPU, memory, and I/O on one chip

• Microprocessors are mostly used for single-function devices

• Microprocessors are more commonly battery-powered

Which part of embedded system architecture directly converts physical data to an electrical signal?

• Actuator

• Sensor

• Processor

• D-A Converter

What is the primary role of the analog-to-digital (A-D) converter in an embedded system?

• To interpret user commands

• To convert digital data into a physical action

• To change analog sensor data into digital signals

• To store processed outputs in memory

Which statement accurately reflects standalone embedded systems?

• They rely on a network to function properly

• They can perform multiple unrelated tasks

• They work independently without needing a host system

• They always need constant user input to operate

Why might an embedded system be difficult to upgrade?

• It uses general-purpose hardware

• It usually needs hardware changes to update software

• It runs on the cloud, making local updates impossible

• Its multi-core processors are complex to program

Which is NOT typically an advantage of embedded systems?

• Cost-effective design for specific tasks

• Easier to house inside devices

• Easily programmable for multiple tasks

• Minimal hardware modifications needed
