About Course

Basic Networking Fundamentals is a comprehensive, professional-level program that teaches how computer networks actually work — from the cables and Wi-Fi signals carrying data, to the addressing systems that let billions of devices find each other, to the security practices that keep those connections safe.

Modeled on the depth of Cisco Networking Academy and CompTIA Network+ foundational content, this course moves students from "my Wi-Fi works" understanding to genuine professional networking literacy — the kind employers expect from IT support staff, help desk technicians, and anyone managing network infrastructure for a small organization.

What You Will Learn

  • Explain how data travels across networks using the OSI and TCP/IP models
  • Understand and configure IP addressing, including basic subnetting
  • Identify and correctly use core networking hardware (routers, switches, access points)
  • Set up and secure a wireless network to professional standards
  • Apply fundamental network security practices to protect against common threats
  • Systematically troubleshoot network connectivity problems

Prerequisites

Basic computer literacy is recommended. Completing the "Computer Maintenance & Troubleshooting Professional Certificate" course first is helpful but not required.

Target Audience

Aspiring IT support technicians and network administrators, small business owners managing their own office networks, and students preparing for further networking certifications.

Estimated Study Time

25–30 hours (5 modules, self-paced)

Difficulty Level

Beginner to Intermediate — builds systematically from foundational concepts to practical, professional-level skill

Certificate

A Bang Ti Lenydoor Professional Certificate is awarded only after completing all lessons, passing all 5 module quizzes, submitting all 5 practical assignments and the final project, and passing the comprehensive final examination with a minimum score of 70%.

Career Opportunities

Network Support Technician, Help Desk Associate, IT Support Specialist, or a strong foundation for further certifications such as CompTIA Network+ or Cisco CCNA.
