I would like to get help to resolve the following case

Last Chance Securities The IT director opened the department staff meeting today by saying, "I've got some good news and some bad news. The good news is that management approved the payroll system project this morning. The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid possible fines and penalties for noncompliance. The bad news is that the system must be installed by January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in advance, the system should have a modular design if possible, and the vice president of finance would like to announce the new system in a year-end report if it is ready by mid-December." Tasks 1. Why is it important to define the project scope? How would you define the scope of the payroll project in this case? 2. Review each constraint and identify its characteristics: present versus future, internal versus exter- nal, and mandatory versus desirable. 3. What…

2. Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.
