Answer:
Major risks include computer security and maintability of the software and hardware components of the computers in these objects.
I may feel more scared if I was riding a roller coaster that was computer controlled because if there were vunerabilities in the computer's software, a hacker could exploit that and remotely have access to the controls of the roller coaster, putting many people's lives at risk.
I think the benefits of computerizing an increasing number of everyday objects outweigh the potential risks.
This is because computers is very reliable and they do exactly what you tell them to do. However, humans are clumsy and can sometimes be extremely stubborn. Computerizing more everyday objects is an overall good thing for society, however, policies and protocols need to be followed to ensure these computerized objects remain secure.

Answer: Please see below as the answer is self-explanatory
Explanation:
Digital phones, normally uses a keyboard, with the digits 0-9, and special characters like # and *.
When the caller presses any keyboard, an electronic circuit within the phone generates two pure sinusoids, of frequencies within the vocal bandwidth (between 300 Hz and 3 khz, roughly), which identifies uniquely (as decoded by the receiving switch) which was the key pressed.
In this way, the switch reconstructs the phone number called, separating country code, area code and the local number as it receives the tones.
This system is called DTMF (dual tone multi frequency).
