All ITF+ Lessons
This page gives you the full CompTIA ITF+ lesson path in one place. If you are new to IT, start at Lesson 1 and move forward in order. The goal is to build real understanding before jumping into A+.
Why start with ITF+?
ITF+ helps you build the vocabulary and mental framework most beginners are missing. Instead of memorizing random facts, you start to understand how computers, operating systems, networking, security, and troubleshooting fit together.
What you’ll cover
Core IT Basics
Hardware, software, operating systems, and how devices work together.
Networking
Foundational networking ideas that prepare you for A+ and beyond.
Security
Safe computing, core protection concepts, and basic security awareness.
Troubleshooting
How to think through problems instead of panicking when things break.
Lesson Path
Follow these in order. Each lesson builds on the previous one.
CompTIA ITF+ • Lesson 1
Start here if you are completely new. This opens the path and sets the foundation for everything after it.
Lesson 2: Software, Operating Systems, and Firmware
Learn how software layers work and how the operating system fits between hardware and applications.
Lesson 3: Networking Basics
Build your first real mental model of how devices connect, communicate, and move data.
Lesson 4: Hardware & Devices (Computer Components)
Understand the major physical components inside and around a computer system.
Lesson 5: Operating Systems, Devices & Data
Continue building practical understanding of operating systems, storage, files, and connected devices.
Lesson 6: Security Basics: Protecting Systems, Data, and Users
Learn the early security habits and concepts every beginner should know.
Lesson 7: Data & Databases (ITF+)
Get comfortable with how data is stored, structured, and used inside systems and databases.
Lesson 8: Programming & Application Development Fundamentals
See how applications are built and why basic programming awareness matters in IT.
Lesson 9: Security Fundamentals
Reinforce the foundational security ideas that prepare you for more advanced topics later.
Lesson 10: Troubleshooting Methodology
Learn how to break problems down logically instead of guessing.
Lesson 11: Databases and Data Basics
Learn how databases organize, store, and manage information used by applications and systems.
Lesson 12: Final Review and Next Steps
Review the major concepts from ITF+ and prepare for your next certification path such as A+.
After ITF+
Once you finish this path, A+ is the strongest next step for building real troubleshooting and job-ready support skills.
