Grading Information:
The final grade will be determined as follows:
Midterm Examination--------------------- 25%
Final Examination----------------------- 25%
White Paper----------------------------- 25%
Homework and Web Tycho Participation---- 25%
According to the Graduate School grading policy, the following symbols and scale are used:
A = excellent (90-100)
B = good (80-89)
C = passing (70-79)
F = failure (less than 70)
The grade of "B" represents the benchmark for the Graduate School. It indicates the student has demonstrated competency in the subject matter of the course, i.e., has fulfilled all course requirements on time, has a clear grasp of the full range of course materials and concepts, and is able to present and apply these materials and concepts in clear, reasoned, well-organized and grammatically correct responses, whether written or oral.
Only students who full meet this standard and, in addition, who demonstrate exceptional comprehension and application of the course subject matter, merit an "A."
Students who do not meet the benchmark standard of competency fall within the "C" range or lower. They, in effect, have not met graduate level standards. Where this failure is substantial, they earn an "F."

Course Requirements:
1. Examinations. There will be a midterm and a final examination designed to help students master the course content.
2. White Paper.
A. Type of Paper. The paper should examine a topical area approved by the professor. The paper must state a thesis and, based on the research, undertake to prove or disprove that thesis. The paper should review the recent literature (1995-present), distill the fundamental issues, discuss various solutions to the issues raised, identify trends, and formulate the student's own position. Arguments critical of the student's thesis must be evaluated. An adequate literature search is based first on academic journals (e.g., Journal of Data Communications), second on professional journals (e.g., Journal of Systems Management), and last on books and textbooks.
B. Length and Style. The paper should have a body of 10 to 15 pages. The paper must be typed in accordance with Appendix A of the Publication Manual of the American Psychological Association. You must create a format template for it in your word processing software.
C. Term Paper Process. Students may choose to use a structured approach to aid them in completing a successful term paper. Students using this process should turn in developmental products within the first several sessions of the course, such as a concept paper, a proposed bibliography, and an outline. This is optional.
A representative sample of relevant topics includes:
Portals
Tunneling
Sniffers
Cookies
Filters
Next Generation Internet (NGI)
Domain Name System capacity and registration
Electronic Data Interchange (EDI)
Secure Socket Layer (SSL) Encryption

Description of Course Requirements:
Successful graduate students in American universities dedicate approximately three hours of preparation/study time for every hour spent in the face-to-face classroom. Thus, the following course requirements were developed on the assumption that students would be prepared to spend approximately 150 hours of their own time working on them. In an 8-week term, that is the equivalent of a half-time job. Most 14-week graduate distance education courses require at least 10 hours per week of dedicated time, plus time spent in the virtual classroom.
STATEMENT ON WRITING REQUIREMENTS:
Effective managers and leaders are also effective communicators. Written communication is an important element of the total communication process. The Graduate School recognizes and expects exemplary writing to be the norm for course work. To this end, all analyses and papers must demonstrate graduate level writing ability and comply with the format requirements of the Publications Manual of the American Psychological Association. All writing assignments will be graded on the basis of content, logic, analysis, mechanics, organization, and research. Careful attention should be given to source citations, proper listing of references, the use of footnotes, and the presentation of tables and graphs. Work submitted online should follow standard procedures for formatting and citation.
POLICY ON ACADEMIC INTEGRITY:
Academic integrity is central to the learning and teaching process. Students are expected to conduct themselves in a manner that will contribute to the maintenance of academic integrity by making all reasonable efforts to prevent the occurrence of academic dishonesty. Academic dishonesty includes (but is not limited to) obtaining or giving aid on an examination, having unauthorized prior knowledge of an examination, doing work for another student, and plagiarism of all types.
PLAGIARISM:
Plagiarism is the intentional or unintentional presentation of another person's idea or product as one's own. Plagiarism includes, but is not limited to the following: copying verbatim all or part of another's written work; using phrases, charts, figures, illustrations, or mathematical or scientific solutions without citing the source; paraphrasing ideas, conclusions, or research without citing the source; and using all or part of a literary plot, poem, film, musical score, or other artistic product without attributing the work to its creator. Students can avoid unintentional plagiarism by following carefully accepted scholarly practices. Notes taken for papers and research projects should accurately record sources of material to be cited, quoted, paraphrased, or summarized, and papers should acknowledge these sources in footnotes. The penalties for plagiarism include a zero or a grade of F on the work in question, a grade of F in the course, suspension with a file letter, suspension with a transcript notation, or expulsion. Resubmission of course work from previous classes (whether or not taken at UMUC, UMUC-Europe or BSU), partially or in its entirety, is not acceptable in this course and will result in an automatic failure on the assignment.
DISABLED STUDENTS:
Students with disabilities who need to register or request services should contact the Staff Support Team four to six weeks in advance of registration to request and register for services.
COURSE EVALUATIONS:
Feedback on each graduate course and instructor is important to the university, your professor, and to all UMUC students. UMUC has the responsibility to assess the effectiveness of classroom instruction, and each student has the responsibility to provide accurate and timely feedback through completion of the course evaluation form. This is a shared obligation for us all. It is therefore important that you complete the evaluation form for each course you attend. This should be viewed as an additional course and program requirement.
EXTRA CREDIT:
There are no extra credit assignments. Students are expected to do well on the standard assignments.
