The stakes are high. Data networks are more crucial for businesses than ever before: they are the lifeline to the critical financial, healthcare, and information services that need to function at the highest, most secure level. With a CompTIA Network+ certification, you will possess the key skills to troubleshoot, configure and manage these systems and keep your company productive.

According to the U.S. Bureau of Labor Statistics, 12% job growth is expected in network and computer systems over the next seven years. Additionally, CompTIA Network+ professionals are known to excel in their job: 53% of IT and business executives agree that certified staff performs at a higher level than non-certified staff; this according to the CompTIA International Technology Adoption and Workforce Trends report. Global Knowledge’s IT Skills and Salary Report estimates the average salary of a Network+ certified IT professional at about $74,000.


Upon successful completion of this course, students will be able to:

  • Identify the basic components of network theory.
  • Identify the major network communications methods.
  • Identify network data delivery methods.
  • List and describe network media and hardware components.
  • Identify the major types of network implementations.
  • Identify the components of a TCP/IP network implementation.
  • Identify the major services deployed on TCP/IP networks.
  • Identify the components of a LAN implementation.
  • Identify the components of a WAN implementation.
  • Identify major issues and technologies in network security.
  • Identify the components of a remote network implementation.
  • Identify major issues and technologies in disaster recovery.
  • Identify major data storage technologies and implementations.
  • Identify the primary network operating systems.
  • Explore tools, methods, and techniques used in managing a network.
  • Describe how to troubleshoot network issues.

This course will build on your existing user-level knowledge and experience with personal computer operating systems and networks to present fundamental skills and concepts that you will use on the job in any type of networking career. If you are pursuing a CompTIA technical certification path, the CompTIA A+ certification is an excellent first step to take before preparing for the CompTIA Network+ certification.


CompTIA A+ Certification or equivalent knowledge and some practical industry experience in networking are strongly recommended.


This course prepares the student for the CompTIA Network+ examination.

In order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is CompTIA A+ Essentials, exam number 220-901. Objectives for the CompTIA A+ Essentials examination are available at www.comptia.org. The CompTIA A+ 220-902 exam, Practical Application, is the second exam required in order for CompTIA A+ certification candidates to complete their certification.

The CompTIA A+ Practical Application exam measures the necessary competencies for an entry-level IT professional who has hands-on experience in the lab or the field. Successful candidates will have the skills required to install, configure, upgrade, and maintain PC workstations, the Windows OS and SOHO networks. The successful candidate will utilize troubleshooting techniques and tools to effectively and efficiently resolve PC, OS, and network connectivity issues and implement security practices. Job titles in some organizations which are descriptive of the role of this individual may be: Enterprise technician, IT administrator, field service technician, PC or Support technician, etc. Ideally, the CompTIA A+ Practical Application candidate has already passed the CompTIA A+ Essentials Exam.
