You Learned How to Fix Computers.
Now Learn How They Talk.
A+ taught you how to troubleshoot devices.
Network+ teaches you how systems connect, communicate, and fail across networks.
What Changes Now?
In A+, most problems lived inside a single machine. In Network+, problems live between systems.
In A+
- Fix slow PCs
- Restart services
- Check hardware
- Local troubleshooting
In Network+
- Why can’t this device reach the server?
- Is it DNS, IP, or gateway?
- Where does traffic break?
- End-to-end troubleshooting
The Mindset Shift
You are no longer just fixing devices.
You are tracing paths.
- Device → Switch → Router → Internet
- Client → Server → Service
- User → Request → Response
Every issue becomes: “Where is the break in the chain?”
What You’ll Learn in Network+
- IP Addressing (IPv4 / Subnetting)
- Ports & Protocols
- Switches, Routers, Firewalls
- DNS, DHCP, NAT
- Network Troubleshooting
- Real-world traffic flow
What You Should Be Able To Do After This
- Diagnose why a device has no internet
- Identify IP vs DNS vs routing issues
- Understand how data moves across networks
- Think like a real network technician
