Data Communication and Distributed Networks
DCDN300 — Data Communication & Distributed Networks, 3.0 hours
This course will provide students with a clear understanding of how networks, from LANs to the massive and global Internet, are built and how we can use computers to share information and communicate with one another. Topics included communication codes, transmission methods, interfacing, error detection, communication protocols, communications architectures, switching methods, and network types.
Program Objectives
- Define basic terminology of computer networks and the common examples of computer networks.
- Distinguish between data and signals and differentiate between analog data and analog signals.
- Understand the cabled and wireless media and their areas of application.
- Explain how to interface computer to peripheral devices and the different forms of multiplexing.
- Identify different types of noise in computer networks, detection techniques as well as prevention mechanisms.
- Understand the primary function of LAN, basic components of wireless LAN and distinguish between MAN &WAN.
- Describe the major Internet applications and services and the basic elements of a telephone system.
- Recognize the basic forms of system attacks, techniques used to secure the network and how to design and manage the network.

Academic Integrity/ Plagiarism
Cheating (dishonestly taking the knowledge of another person whether on a test or an assignment and presenting it as your work) and plagiarism (to take and pass off as one's own the ideas or writing of another) are a serious issue. While it is legitimate to talk to others about your assignments and incorporate suggestions, do not let others "write" your assignments in the name of peer review or "borrow" sections or whole assignments written by others. We do get ideas from life experiences and what we read but be careful that you interpret these ideas and make them your own.
I am aware that many types of assignments are available on the internet and will check these sources when there is legitimate suspicion.
Penalty is a zero on the assignment. In cases where there is a major or continuous breach of trust, further discipline, such as an "F" in the course, may be necessary.
The major consequence of any form of cheating is damage to your character and the result of trust and respect.
Disability Accommodations
Students who have a disability and wish to request an academic accommodation should contact Jim Gepperth, the Disabilities Services Coordinator and Academic Dean. The student can request an accommodation at any time although it is encouraged to do so early in the enrollment process. The student should complete an accommodation request form which begins a conversation between the school and the student regarding the nature of their disability and an accommodation that would help the student succeed in their program. The school may request documentation regarding the disability to address the accommodation request effectively. The school will communicate to the student the type of accommodation arranged. This process typically follows a team approach, bringing together persons from the academic department (including the instructor) and personnel from other departments as necessary. Additional information on disability accommodations may be found in the Lakewood University Catalog.
