2 COURSE DESCRIPTION: This course provides an overview of data communications through a combination of theory and practical labs. It builds on the fundamental concepts used in data and network communication technology presented in Networking Technologies. The course is designed to make the student easily understand the concepts in data communications and put them in practice in laboratory. COURSE LEARNING OUTCOMES: Upon successful completion of this course, students will be able to: Apply fundamental data-communication concepts and terminology Analyze commonly used signals in communication systems in time and frequency domain Utilize the various communication networks and signaling protocols Compare the transmission mediums and their capacity Provide details on various digital modulation schemes and multi-user access techniques Describe error detection and correction schemes for data communication Describe the high speed data communication networks ESSENTIAL EMPLOYABILITY SKILLS (EES): This course supports the students ability to: Communicate clearly, concisely and correctly in the written, spoken and visual form that fulfills the purpose and meets the needs of audiences. Use a variety of computer hardware and software, and other technological tools appropriate and necessary to the performance of tasks. Interact with others in groups or teams in ways that contribute to effective working relationships and the achievement of goals. Evaluate her or his own thinking throughout the steps and processes used in problem solving and decisionmaking. Collect, analyze and organize relevant and necessary information from a variety of sources. PRIOR LEARNING ASSESSMENT & RECOGNITION PROCESS (ES): This course is eligible for PLAR through the Registrar and SETAS offices. Assessment of portfolio and/or testing may be discussed with faculty EVALUATION & GRADING SYSTEM: Midterm Test 30% Lab Work 30% Project 10% Final Exam 30% STUDENT ACCOMMODATION: All students have the right to study in an environment that is free from discrimination and/or harassment. It is College Policy to provide accommodation based on grounds defined in the Ontario Human Rights Code. Accommodation may include changes or modifications to standard practices. Students with disabilities who require academic accommodations must register with the Centre for Student with Disabilities. Please see the Centre for Students with Disabilities for details. Students requiring accommodation based on human rights grounds should talk with their professors as early as possible. Details are available on the Centennial College website ( ). 1/15/2009 THIS COURSE ADHERES TO ALL COLLEGE POLICIES (See College Calendar) Page 2

3 If students are unable to write an examination due to a medical problem or unforeseen family problems, they should immediately contact their professor or program Chair for advice. In exceptional and well documented circumstances (e.g. unexpected family problems, serious illness, or death of a close family member), students should be able to write a make-up examination to replace an examination missed. TEXT AND OTHER INSTRUCTIONAL/LEARNING MATERIALS: Data Communications and Networking, by Behrouz A. Forouzan, McGraw-Hill ISBN: Reference Books Understanding Data Communications & Networks, by Shay, ITP, ISBN X Caveat The College will use reasonable effort to deliver the course details as described in the following table. However, the timing of the delivery can vary from week to week. For example, some topics could be combined into one week or a single topic could be expanded over several weeks. In addition, external factors such as weather and power failure can also influence the timing and availability of the content. Students are encouraged to read the course materials prior to attending classes in order to enhance their overall learning experience. USE OF DICTIONARIES Students are not allowed to use dictionaries during tests and examinations 1/15/2009 THIS COURSE ADHERES TO ALL COLLEGE POLICIES (See College Calendar) Page 3

4 College Policies POLICY STATEMENTS The following statements are selected from Centennial College policies approved by the Board of Governors. Student Responsibilities Students are expected to know the contents of the course outline and to discuss with the professor any areas where clarification is required. Students should keep all course outlines for each course taken at Centennial College. These may be used to apply for transfer of credit to other educational institutions. A fee may be charged for additional or replacement copies. Other Policies Students should familiarize themselves with all College Policies that cover students rights, responsibilities, and the Academic Appeal process. For further information, consult the Academic Matters Section in the full-time and Continuing Education calendars. The Academic Appeal Application form is available from any Enrolment Services Office. Proof of Student Status Students must produce official photo identification at any time during the semester when requested to do so by any professor. (The official piece is the Centennial Student Card.) Continuing Education students do not have Centennial Student Cards, and so they may use other forms of photo identification, such as a driver s license, health card, or other government-issued photo identification. Final Examinations When writing a test or examination, students must put their official photo-id cards in full view for review by the invigilator. Students who do not have official photo-id will be permitted to write the examination with a substitute photo-id, but they will be required to produce photo-id at the program or department office within 24 hours or the next business day following the examination, or else the examination results will be void. More Final Examination Policies are available at Academic Progression Policy for Diploma and Certificate Programs: College Academic Standings will be applied. Please see Academic Policies and Procedures, Full-Time Calendar. Faculty Consultation Professors are available to see students outside of class time. Students can contact professors via voice mail, , or through their program or department office. Information regarding how to contact teachers will be provided at the beginning of the course and is also available in the program or department office. Human Rights Statement It is the policy of the College that all programs will strive for a learning, teaching, and working environment that promotes inclusion, understanding, and respect for all students and employees, consistent with the Ontario Human Rights Code and Centennial College's Statement of Diversity. 1/15/2009 THIS COURSE ADHERES TO ALL COLLEGE POLICIES (See College Calendar) Page 4
