Smart vs Intelligent vs Adaptive vs Advance (etc) Embedded Devices
Most are marketing BS, intelligent, smart, innovative, advanced, mean absolutely nothing.

Some of the more precise things might mean at least a bit of what they intend to convey, but how well they execute that is another matter. 

Adaptive - it should self adjust to something or other. ADSL modems test the quality of the line before deciding on a speed, does that count?

Fault tolerant - what faults, what degree of service after faults? Doesn't catch fire, automatically reconnects after disconnection? Totally meaningless without details.

Self-healing - after what faults? Does it have RAID drives and can survive a drive failure, or is it two complete computers, or does it test its RAM from time to time and avoid bad cells? Totally different threat models and behaviour.

As the details would be complicated, with luck defined in the data sheet, any headline description is not going to tell you anything meaningful. Their proper use is limited to pointing you towards the data sheet. Their main use is to get you to notice the product, and hopefully buy it without investigating the details.
