Your Answer for Question 1:
Since data is essentially just sequences of 0s and 1s, someone could tweak these sequences to produce different numbers or instructions that the programmer did not intend.  It could be prevented by storing data in registers than cannot be modified once the information is put in, rendering it impossible for someone to disrupt the sequence of instructions directly.

Your Answer for Question 2:
A subnormal is the inaccuracy that can result from the addition and subtraction of extremely large and small numbers.  It can vastly affect that outcomes of data.

Your Answer for Question 3:
the binary representation of 0.5 would include more bits than that of 1.0 because in floating point it would be changed into 5.0 x 10^-1, and 5 in binary has more significant bits than 1(0101 instead of (0001), which would increase the accuracy of the calculation.

Your Answer for Question 4:
Adhering to the standard would allow backwards compatibility, as well as simplify the lives of programmers who have been accustomed to the system.  THe disadvantage of adhering to old systems is that modern systems tend to produce different solutions that may be more efficient.
