Introduction to Telecommunications and Data Networking

Course Objectives And Target Audience
Introduction to Telecommunications and Data Networking has been designed to provide an introductory-level exposure to core computer connectivity technology. The course will appeal to:

• people who have been recently assigned to a role that requires a working knowledge of data communications concepts.
• people who wish to develop a solid, working knowledge of current networking technology, but lack the background for our intermediate level Network Solutions; LANs and LAN Connectivity program.
• people who have a work-environment need to be literate with the terminology and concepts that apply to telecommunications technology.
• people responsible for managing and/or administering LAN/WAN data networks
• people newly appointed to responsibilities in this area, having no previous background in the subject
• executives who find that this technology has passed them by, and who need a concise exposure to the elements of this increasingly challenging field.

What Students Can Expect to Gain From Attending
Students who attend our seminars consistently observe that they appreciate the systematic exposure to the many dimensions of the technology, and the emphasis on terminology that goes with it. Many people have had exposure to one or more portions of the subject, but the unifying consistency of an organized presentation on the subject is clearly valued.

The specific terminology of this field is challenging to beginners. A key objective of this seminar program is a demystification of terminology. No brief seminar on any large topic can make experts of the participants. Realistically, in this short exposure, students will acquire:

• a current working perspective, and introduction to telecommunications and data communications
• a practical sense of the relationship between the various dimensions of the subject
• a chance to rationalize their own work situation with the procedures and methods used in industry
• an appreciation of significant trends in the industry, and a vision of what aspects of these technologies are in process of significant, positive change

Format and Prerequisites
Introduction to Telecommunications and Data Networking was designed as a two-day course -- comprising approximately 12 hours of instruction.

A permanent, comprehensive workbook is included for each attendee -- which provides a work-along class reference manual with a cross-referenced, comprehensive subject index, encyclopedic glossary and recommended reading catalog.

There are no technical prerequisites for this program. Introduction to Telecommunications and Data Networking has been designed to start as an entry-level treatment of the subject.

Recommended Further Study
This seminar is designed to provide the necessary background for, and lead directly into our intermediate-level Network Solutions; LANs and LAN Connectivity.
