Your Answer for Question 1:
Since data and instructions are represented the same way, data can be confused as an instruction and that could run an unwanted instruction.  One way to avoid this is to represent data and instructions differently.  The tradeoff for this would be that the processor would have to be more complex and thus slower.

Your Answer for Question 2:
A subnornmal is a denormalized number.  They have the same epxponent as zero but a nonzero significand, and they allow gradual underflow so numbers smaller than those possible in regular floating point can be represented.

Your Answer for Question 3:
This technique compensated for the fact that some machines lacked a guard bit for double precision floating point numbers, so there would be less round-off errors.

Your Answer for Question 4:
for: there has been no better solution for flaoting points than the IEEE 754 standard

against: most bits in the exponent field would be wasted since they aren't used as often and the processor would be made more complex with the specialized floating point hardware
