Data Communications I - The Fundamentals

Description

This is an introductory level class for people with little prior exposure to data communications systems but who need an understanding of the technology's fundamentals as well as industry buzzwords.

The class begins by covering the base principles of data including such topics as bits and their origin, binary theory, character code sets, the functions of transmitters and receivers, and a solid discussion of data protocols including how packets and frames are formed. This knowledge is then used to understand particular implementations of data systems including local area networks or LANs, Ethernet, wide area networks or WANs, packet switching, and frame relay and asynchronous transfer mode technologies. A discussion of office wiring and unshielded twisted pair categories of wire is also included.

Prerequisites: None

Data Communications II - Data Networking

Description

This class addresses data networking concepts and is a logical follow-on to Data Communications I for those needing an understanding of the issues of building and running a data network.

The class begins with a general discussion of the concepts of data architectures and examples of their implementation with an emphasis on TCP/IP. A good description of IP-based networking follows including IP address structure, assigning addresses, packet routing and packet flow control. The next section covers the important operational subjects required of modern networks such as maintaining good performance and quality, achieving good security and applying good management practices.
