Understanding Network Technology
This course is designed to provide a comprehensive understanding of network fundamentals. Students
will gain an understanding of; protocol models, network configurations, physical transport media, network
devices and applications.
Prerequisite:
FT-2 level Courses
Target Audience:
•
Entry level cable personnel – field technicians, NOC personnel and managers thereof
Requirements for Successful Course Completion:
•
•
Module quizzes 70% or higher
Course final test 70% or higher
You may take the final course test up to 3 times.
Format and Schedule:
The course is delivered online via the SCTE virtual classroom over 16 weeks or 4 months, during which
participants view web based course materials and complete assessments (quizzes) at a time that is
convenient for them. Participants can contact the instructor when they have questions.
Participants spend approximately 2 - 4 hours per week, on average, completing the various course
activities in order to maximize the learning benefits. 100% of the schedule is determined by the participant
(viewing online materials and completing quizzes).
System Requirements: A high speed Internet connection, Internet browser (e.g.: Google CHROME) with
flash or HTML5. For tablet access, HTML5 can be used to gain access to online content.
Upon Successful Course Completion Participants will Receive
