30 Questions
Actuators affect the digital world.
False
The sensor feeds data directly to the actuator.
False
An analog to digital converter is needed if the sensor directly senses digital data.
False
The processing system is a digital machine.
True
A D to A converter is needed when giving data to a digital environment.
False
Actuators can provide direct control in some cases.
True
In order to keep the speed constant when friction increases, less force needs to be applied.
False
IoT stands for Internet of Technology.
False
Embedded systems usually consist of processing units, sensors, and actuators.
True
Each system in IoT has its own dedicated internet connection.
False
IoT systems can only communicate with systems within close range.
False
Friction decreasing on a road requires more force to maintain the same speed.
False
A microcontroller is a type of processor.
True
A multiplier can be considered as a processor according to the text.
True
Reactive systems react to non-urgent events.
False
Transformational systems are involved in image processing.
True
All processors mentioned in the text can only be implemented in hardware.
False
Reactive systems do not work continuously but only when an event occurs.
True
An answering machine is an example of a system that runs a single program repeatedly.
True
General purpose systems are tightly constrained and can only serve a single purpose.
False
Tightly constrained systems like answering machines must have high cost and consume a lot of power.
False
Tightly constrained systems are usually preferred to be portable and run on batteries.
True
Tightly constrained systems should always operate at very slow speeds.
False
Programs in tightly constrained systems are typically written once and then run repeatedly in embedded processors.
True
A real-time system will not cause any catastrophe if the picture capture is slow.
True
If the image capture process is very slow, it is classified as hard real-time.
False
Communication is not an important part of the embedded system ecosystem.
False
The CCD processor data is communicated through a bus in the embedded system architecture.
True
The JPEG codec is responsible for converting and compressing data in the embedded system.
True
The UART function in the embedded system architecture converts serial data to parallel data.
False
