Does the presence of an I/O driver imply that the computer executing the driver is embedded?
No, never
Why are PDAs not considered embedded systems?
They run office productivity applications
What type of system is a cell phone microprocessor considered to be?
Embedded system
Why are computers in a big phased-array radar considered embedded systems?
They control specific hardware in the radar
Which type of computer can be classified as an embedded system?
Control computer for an industrial machine
What is a key distinguishing feature of a microprocessor?
Its CPU components are all on a single chip.
Which statement best describes the relationship between microprocessors in the same family?
Programs written for one machine can run on any other in the family.
Is a traditional flight management system (FMS) embedded if it is not connected to the avionics and is used only for logistics computations?
No, because it can be easily replaced by a laptop for logistics computations.
Are the computers in a hardware-in-the-loop (HIL) simulator considered embedded systems?
Yes, because they control the simulator and the testing equipment.
What characteristic tends to increase as you move from lower to higher family members of a microprocessor?
Increasing cost
Is the computer controlling a pacemaker considered an embedded system?
Yes, as it is part of a larger system involving the person's heart.
Why are programs that understand physics and/or hardware not considered embedded systems?
Because they are integral components of larger systems.
Does the computer controlling fuel injection in an automobile engine qualify as an embedded system?
Yes, it is embedded as it controls a critical component of the engine.
Is an internal microprocessor controlling a disk drive an example of an embedded system?
Yes, because it is an integral part of a larger system.
In what context can a flight management system be considered embedded?
If it is tightly integrated into the avionics system for critical operations.
Why are embedded systems crucial in controlling pacemakers and automobile engines?
To enable precise monitoring and control of critical functions.
