Subject Title
Introduction to Data Communication Technology

Subject Description
This course is an introduction to the field of Telecommunications and Data Communications. The course focuses on the practical aspects of implementation, installation and maintenance of Local Area Networks and Wide Area Networks. Ethernet and a practical understanding of components, hardware requirements, cabling, software and security/management features needed to build and operate a LAN will be learned. Wide Area technologies will also be discussed, directed towards the development of a practical understanding of the functions and abilities of connectivity devices such as switches, bridges and routers.

Credit Status
1 Credit for CNS/CTY Diploma Program

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Explain networking terminology and concepts of data communication to provide technical support to non-technical network users.

2. Recommend networking devices to address networking challenges.

3. Identify how industry networking models provide standards of communication that allow networking professionals to communicate using a common    terminology that is specific to network design and diagnostics.

4. Build a Local Area Network using network cables and devices.

5. Configure network devices, protocols, workstations and servers to establish network connectivity and reliable resource access.
