Course Overview

Fundamentals of data communications and computer network protocols and standards. It provides a basic understanding of data communication systems with practical examples of communication networks as applied in engineering technology. Study of OSI and TCP/IP models, data transmissions, transmission media, network topologies, network cabling system, IP address, TCP/IP suite, local area networks (LANs), wide area networks (WANs), wireless network, and network security. Students carry out experiments using modern hardware and software networking tools. In particular, this semester will focus on the content required to obtain the CompTIA’s Network+ and TestOut’s Network Pro certifications.

Course Learning Outcomes

Upon completing this course, the learner will be able to meet these overall objectives:

  1. Identify network cable and network types
  2. Identify common network standards
  3. Understand how data and signals are transmitted
  4. Identify wired and wireless network components
  5. Set up a wired or wireless network
  6. Manage static and IP addressing
  7. Manage network protocols
  8. Troubleshoot common network issues

The purpose of the course is to provide the student with the equivalent knowledge of an entry-level network administrator with 9-12 months of experience.

About the Certifications

The purpose of a networking certification is to validate and demonstrate that the recipient has the required networking skills and experience to manage basic network infrastructure. This course meets the specification of two industry certification programs:

  • TestOut’s Network Pro certification measures the student’s ability to perform real-world job skills using the Windows operating system and common networking hardware.
  • CompTIA’s Network+ certification is an international vendor-neutral certification with a broad-based knowledge base. Many other vendor-specific certifications require Network+ certification (or its equivalent) as a foundation.


  • Knowledge of PC hardware installation and configuration.
  • Knowledge of using and administering a Windows client computer.

  • There is no make-up time for missing assignments. Nothing will be accepted after the due date.

In-class Exams

  • The Mid Term exam will cover modules 1 to 5 from TestOut Network Pro training material
  • The final exam will be a practice test covering all the content expected in a real Network Pro or Network+ exam.

In-class Networking Lab Assignments

The in-class laboratory work has to be completed in classroom time. No late submissions. Lab assignments are graded on a scale from 0 to 100 according to the following criteria:

Criteria Grade
