Essential Understanding of Network Technology

3 min read
Understanding Network Technology is the ultimate introductory course designed to provide participants with the fundamentals of networking. The course covers the concepts for LAN and WAN networks, their architecture and network components. In addition to learning the core concepts, participants will learn the purpose of protocols, networking addressing and overview of digital media.


Target Audience:

  • Customer Facing Installers
  • Customer Facing Technicians
  • Service Technicians
  • Executives
  • Marketing managers
  • Public and government affairs managers
  • Customer service managers
  • Anyone in a nontechnical management role who needs high-level knowledge of the technologies used in networks

Included in the Course:

  • Engaging and Interactive LightningMod™ to prepare learner for training
  • In-depth interactive eBook modules
  • CORTEX mobile app to access eBook modules in the field
  • Module assessments
  • Course final exam
  • Fun VirtuGame™ to improve absorption and retention of competencies
  • SCTE·ISBE course completion certificate
  • 1 recertification units (RUs) towards SCTE·ISBE certification renewal

Format and Schedule:

The course is delivered online via the SCTE·ISBE virtual classroom, or it may be completed in 1 day (8 hours) as an onsite.

Online learners interact with web based course materials and complete assessments (quizzes) at a time that is convenient for them. Learners may also contact the instructor when they have questions.

SCTE·ISBE recommends learners spend approximately 1 – 2 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 learners (interacting with online materials, completing quizzes and a final exam).
