Embedded Systems: Fundamentals Quiz Embedded Systems QuizTime Left: 15:00Q1: How is our day-to-day life changing with technology? Our day-to-day life is becoming more and more dependent on “Embedded Systems” and Digital gadgets. Technology is making life slower. We are becoming less dependent on gadgets.Q2: How are embedded technologies affecting our daily lives? Even without our knowledge, embedded technologies are permeating every aspect of our daily lives. They only affect mobile phones. They are not part of our daily life.Q3: What devices or gadgets are we habituated to using? Refrigerators, washing machines, microwave ovens, air conditioning, television, music systems, etc. Only mobile phones. Typewriters, floppy disks, pagers.Q4: What embedded technologies are found in vehicles? Headlamp controllers, engine controllers, ignition control systems, Anti-lock braking systems (ABS), airbag control systems, etc. Bluetooth speakers and USB ports. Solar panels.Q5: Are people generally aware of embedded systems? Most of the time we are totally unaware or ignorant of these intelligent embedded systems. Everyone is fully aware. They are never used.Q6: What will this tutorial help us understand? In this tutorial, our understanding will be expanded to include these intelligent systems, which are essentially embedded systems only. Only about computers. Only about sensors.Q7: What is a system? A system is made up of a number of interconnected or interacting parts that operate in accordance with a predetermined set of guidelines to create a cohesive whole. A single machine. Only software.Q8: How does a system operate? It is a setup where each unit works together to complete a task while adhering to a set of rules that are computed in real-time. It works randomly. It does not follow rules.Q9: What is another description of a system? It is also a manner of functioning, organizing, or carrying out a single or a number of tasks in accordance with a predetermined plan. It is disorganized. It is random action.Q10: What is an Embedded System? An Embedded System is a microprocessor or microcontroller or FPGA-based hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. It is only a microcontroller. It is random software.Q11: What is another definition of an Embedded System? An Embedded System can be defined as an Electronic/Electro-mechanical system designed to perform a specific function and is a combination of both hardware & software. It is only software. It is only hardware.Q12: What is the third definition of an Embedded System? It can also be defined as a combination of hardware and software which together form a component of a larger machine. It is a random device. It is a virtual system only.Q13: What are the three major components of a typical embedded system? Hardware, Application Software, Real-Time Operating system (RTOS). CPU, GPU, RAM. Monitor, Keyboard, Mouse.Q14: What is hardware in an embedded system? Hardware is a physically used component that is connected to the embedded system for interaction between the environment and the processing or controlling unit. It consists of sensors, microcontrollers, power supplies, actuators, etc. Only wires and circuits. Only the display unit.Q15: What is application software in an embedded system? Application software enables the user to run a variety of programs on an embedded device by altering the installed code. It is only the BIOS. It stores electricity.Q16: What is RTOS? RTOS is an operating system intended to serve real-time applications that process data as it is received by the input of an embedded system. It acts as an interface between hardware and application software to perform a few tasks by ensuring that the tasks will always be executed before the deadline. It is a storage device. It is a graphics driver.Q17: What is the basic structure of a typical embedded system? Sensor, A-D Converter, Processors/ ASICs/ FPGAs/ DSPs or SoCs, Memory elements, D-A Converter, Actuator. Keyboard, CPU, Monitor. Motherboard, RAM, Hard disk.Q18: What does a sensor do? A sensor aids in measuring the physical quantity and converting it to an electrical signal. Moreover, it records the measured quantity in the memory. It converts digital to analog. It stores data permanently.Q19: What is an A-D converter? An A-D converter is an integrated circuit used to transform the analog signal (continuous form) into a digital signal (discrete form). It converts digital to analog. It is a storage device.Q20: What is memory? Memory is a device that is used to store information for immediate use or future use in a system. It converts signals. It controls motors.Q21: What types of memory are found in embedded systems? i) Volatile memory (requires power to maintain the stored information) ii) Nonvolatile memory (retain the stored information even after the power is removed). Temporary memory only. Cache memory only.Q22: What is embedded firmware? A sort of flash memory known as embedded firmware is used to store specific software that runs on a chip inside an embedded device to control functionality. It is RAM. It is CPU cache.Q23: What is the role of Processors/ ASICs/ FPGAs/ DSPs/ SoCs? This is the most important unit of an Embedded System. This unit processes the data to measure the output and store it in the memory. It only displays data. It is only a power supply.Q24: What is a D-A converter? D-A converter (A digital-to-analog converter) helps us to convert the digital data fed by the processor to analog data. It converts analog to digital. It stores permanent data.Q25: What does an actuator do? An actuator enables us to verify the D-A converter’s output against the actual output it has stored, and it saves the approved output to memory. It stores electricity. It generates sound.Submit
