Analog

Question 2

Two's complement representation is a signed integer representation that does not suffer from the problem of two zeros.

Accepted Answer

A) True 
 B)False  True

Question 3

Explain what an arithmetic overflow is and what its significance in computer science is.

Accepted Answer

Arithmetic overflow occurs when there is an attempt to represent an integer that exceeds the maximum allowable value. No matter how many bits are ultimately used, there is always a maximum value beyond which the computer cannot correctly represent any integer. This characteristic is one of the major differences between the disciplines of mathematics and computer science. In mathematics, a quantity may usually take on any value, no matter how large. Computer science must deal with a finite-and sometimes quite limited-set of possible representations, and it must handle the errors that occur when those limits are exceeded.
