Basic Data Communications

Learn the Answers to Key Questions!

Basic Data Communications has been written to teach you the structure of of computer networks, how they operate and the integral role they play in today's office environment. These are fundamental concepts since voice, data and image-based information is transmitted within offices, from site to site and throughout the world.

This comprehensive 14 hour course consists of 10 easy to understand modules. Each module is designed to increase your technical knowledge of key communication terms, transmission technologies, types of network hardware and software, basic tools of network management, security issues, the importance of the Internet and emerging technologies.
