Explanation / Answer
A microcontroller is
a single chip, and it follows instructions. It also reads information and communicates.
So, the answer is: e) all of the above
For engine control, a microcontroller can
a) use a sensor to measure oxygen level of exhaust True
c) indirectly move a piston by sending signals to other engine components True
d) monitor coolant temperature True
So, the answer is: f) a, c,d only
Microcontrollers store information in the form of
b) binary and hexadecimal numbers At the lower level they'll be stored in binary, but for
convenience hexadecimal numbers are also accepted.
Charles Babbage's Analytical Engine included
b) program control by means of looping and branching
c) arithmetic and storage units
So, the answer is: e) b and c
When a processor is fabricated using high-density complementary metal-oxide semiconductor (HCMOS) technology, it
uses less power, and has a high tolerance for noisy signals.
Ofcourse it is smaller, and faster.
So, the answer is: e) all of the above
If a microcontroller needs more memory or I/O than are available in the chip, it will need
a) programming port
b) I/O port
c) external memory
d) external data and address lines
e) reset line
f) reset line and power pin
The following is an example of one byte stored in memory
One byte is 8 bits. So, the answer is: c) 10100011
