Computer Networks: Wholeness on the move.

COMPUTER NETWORKS:
Wholeness on the move. GOAL
The goal of the course is to learn the concepts and terminology of computer networks. We will explore how networks work, and what are their limitations. A secondary goal is to gain experience in writing networked applications.

OBJECTIVES
1. Gain familiarity and knowledge of the predominant network technologies and applications in use today, and the likely successors to these technologies. 2. Understand how networks are implemented--what sort of hardware is used, how it works, and how one implements the software that turns the hardware components into a useful network. 3. Understand how application programs interface with and use network protocols, and develop a series of simple programs that illustrate basic techniques of networked software applications. 4. Gain a deeper understanding of the flow of Creative Intelligence in our own awareness and as expressed in computer network design.

THEMES:
1. 2. 3. 4. Laying the foundation: Applying the knowledge of natural law. Protocols and services: Unity and diversity. Network Programming: Knowledge leads to action, and action leads to fulfillment. Security Issues in Network communication: Purification and integration lead to growth.

EVALUATION CRITERIA
The course grade will be based on two examinations, quizzes, lab assignments, class participation, and the Professional Etiquette evaluation with the following weights: Professional Etiquette Quizzes and Labs Report or Presentation Midterm Exam Final Exam 3% 15% 7% 40% 35%

Attendance at all class sessions including labs is required. Unexcused absences or tardiness will reduce a student's final grade.

Weeks Thirteen, Fourteen and Fifteen:
Review for Final Examination (Study, finishing up labs etc.)

Week Sixteen:
Final Examination

CLASS PARTICIPATION Class participation is essential to the success of the course. Class participation includes regular correspondence with the faculty and the DE office, interaction with fellow students and faculty through the course newsgroup and timely delivery of labs and assignments. PROFESSIONAL ETIQUETTE Proper etiquette is essential to our personal and professional success, and the college years are an ideal time to cultivate these values. To give attention and importance to this, several fundamental values of etiquette are built into the grading system. The components of professional etiquette are class participation, timely delivery and exam attendance. ACADEMIC HONESTY The purpose of our homework and lab assignments is to give each student practical experience in applying the knowledge gained from lectures and readings. This hands-on experience is needed to learn the details of how to apply the knowledge. Therefore, it is against academic policy to copy, or share with others, any homework or lab projects that are assigned as individual work You may discuss the course material, concepts, or ideas with other students. You may review together the relevant topics from lectures or readings to help understand the principles required to start a programming assignment. You can prepare for the exam together, discussing and working on various problems and expected questions. In essence, you can collaborate freely in any course-related work that is not required for submission and evaluated by the instructor. Under no circumstances should you post your lab or homework solutions on a course newsgroup, send via email, or in any other way distribute to others. Every student is expected to work individually on his or her own lab project, exams, and anything else being evaluated as part of the course grade. If you are found to have violated this policy for a quiz, homework or lab assignment, then you will receive no credit for the assignment. If the violation occurs for an exam, you will receive no credit for the course, and be subject to disciplinary measures by the Dean of Students, with possible dismissal from the graduate program. Do your own work, and enjoy the process of learning.
