Assignment 2 Theory Introduction
Researching Your Answers
Most requirements of this assignment will require you to research answers from your text book (you must read the text book to get some answers), from the Internet, from a video or any other reasonable source. Many Internet sources, video links, text book and Blackboard presentations are provided in this document to help you START your research.

Assignments are always a great place to read and reference your text book. May students assume that they should start by reading the text book. While this reading the text book is ALWAYS at great idea, the following assignment questions may help you focus on what is important in this course . One strategy is to review an assignment question for important keywords, e.g., multitasking, Procedure Division, virtualization, etc. Then look for those key words in either 1) your text book "detailed" table of contents in the beginning of the book, or 2) in the index at the end of the book. Some text books have key word glossaries at the end of the chapter or end of the book.

Every semester the Internet sources, e.g., a Google keyword search, or Internet video, e.g., a YouTube keyword search may be improved. Better students start with research sources provided in this assignment, and then search for improved or updated answers. While your objective may be to demonstrate your knowledge to EARN an excellent grade on this assignment, better students are always looking towards the future to impress internship and career recruiters for those interesting and high entry-level salaries. Employers don't pay you for a grade in any single class or assignment. Employers will pay you BIG MONEY for demonstrated knowledge or skills. Hopefully, this assignment will prepare you.

A single research source maybe very incomplete or the format or the content may not be appropriate for some required answers. Some students do not READ the text book or review the Blackboard presentations provided to you in Blackboard. Some answers are only available from Blackboard presentations or update documents. When assignment requirements may be only answered by viewing a YouTube video, you will be notified.

You may cut-and-paste answers whenever appropriate. You MUST synthesize your answers to include multiple sources. I would be impressed that you consult a Google image search and paste and appropriate image to supplement your answer.

While I permit cut-and-paste, I do expect you use your own words so that you:

1. Organize the answer

2. Demonstrate that you have read what you have cut-and-pasted

3. Use any means that clearly displays that you have gained knowledge.

A Little Advice Before you start
There is NO requirement to read each reference link or view each video in detail. Some of the links will have overlapping content. Some links will provide more information than the question requirements, but employers consider these topics to be minimal knowledge of a RMU CIS graduate.

It is recommended to visit each reference link and overview the content. Then read each question and return to each reference link or video as needed. You may supplement your answers with content from your text book by using a question keyword and looking up in the glossary or index in the back of the book. PDF text books can be easily searched for keywords.

It is not required to read your text books before working on this assignment unless specified in a requirement. Text book contents are used to support quiz questions (which contain the answers), which are used on the tests. The reference links and videos are excellent resources.

The topics presented in the course assignments have been highly recommended by two or more employers who recruit RMU CIS students as minimum computer hardware, operating system, and application development knowledge. Employers expect that students should be able to present one or two sentences of the majority of keywords applicable to job requirements in a face-to-face interview.

On the other hand, each assignment is allocated 100 points out of a total of 1000 points. The number of questions or hands-on activity on each assignment varies. Assume that an average assignment has 50 requirement questions. This means that a requirement may be worth 2 points towards your final grade. The bottom line is that missing a few questions will have little effect of your assignment or final grade. Not completing an assignment will generally decrease your final grade by at least a letter grade. Do not waste time on the small problems.
