The embedded systems problem, while serious, has been dramatically overblown. I disagree that it has been overblown. The number of affected systems of importance has been grossly exaggerated. The difficulty of remediating any individual system has been understated. Overall, perhaps not overblown at all but the picture of what the embedded systems problem is all about has been very distorted.
Embedded systems are microchips that control functions in a digital device.
No, this definition is incorrect. Single chip systems implemented with microcontrollers, rather than a microprocessor plus its supporting chips, will usually produce only an annoyance when they fail. Embedded' reflects the fact that they are an integral part of the system. Not a good statement because there is no base number to start with. I would like to see how Gartner developed that number.
