## CIS 512 Week 3 Assignment 1 Numerical Precisio

KaylaShoffner22's insight:

http://www.thestudentsoffortune.com/cis-512-week-3-assignment-1-numerical-precision/

Assignment 1: Numerical Precision

The storage and representation of numbers in a computer can lead to costly mistakes because of precision errors. When using floating point numbers, one must make sure that the correct number of digits is used in a calculation because rounding errors can produce values that lead to errors. Consider the floating point format, exponential format, and binary coded decimal (BCD).

Write a four to five (4-5) page paper in which you:

1. Analyze the floating point format in order to:

a. Determine how floating point numbers are stored in memory.

b. Discuss the ease or difficulty of manipulating and using floating point numbers in arithmetic calculations.

2. Determine whether or not you believe that the floating point format is memory efficient. Provide a rationale to support your answer.

3. Analyze the format used to store numbers using the binary coded decimal format. Determine whether the BCD format is more or less memory efficient than the floating point format.

4. Compare and contrast the BCD format to the floating point format in terms of:

a. precision

b. performance in calculations

c. memory usage

5. Select the format (floating point format, binary coded decimal (BCD), or exponential format) that you would recommend for processing efficiency and explain why.

6. Floating point numbers can introduce rounding errors in the banking industry, which may lead to financial benefit for the bank but not for the customer. Analyze the ethics of knowingly benefitting from rounding errors. Propose a plan on how the rounding error should be handled.

7. Differentiate between the exponential format and the floating point format in terms of:

a. format

b. processing speed

c. accuracy

8. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Assignment must be written in APA style and include in-text citations.

Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

http://www.thestudentsoffortune.com/cis-512-week-10-term-paper-hypervisors/

Term Paper: Hypervisors
Due Week 10 and worth 170 points

A hypervisor is computer hardware platform virtualization software that allows multiple different operating systems (O/S) to share a single hardware host. The configuration is such that each O/S thinks that it has the host’s processors, memory, and other resources all to itself. The hypervisor actually controls the host processors and resources distributing the resources to each O/S depending on need, and ensures that no O/S can disrupt any other O/S.

Write an eight to ten (8-10) page paper in which you:

Examine the technical advantages and disadvantages of using a hypervisor in an enterprise. Compare and contrast the hypervisors from Microsoft (Hyper-V), VMware (ESXi), and Hitachi’s (Virtage). Evaluate the effect of hypervisors on the TCO (Total Cost of Ownership) in an enterprise. Determine whether the implementation of hypervisors has an impact on system administration. (i.e., Would system administrators need re-training?) Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.
