Device Interfaces for Tech+

What "in scope" looks like: given a device or scenario, choose the interface that makes sense (e.g., a modern laptop display output, a wired Ethernet connection, a short-range phone-to-device connection), or identify what a connector/tool is for.

Interfaces Overview

Explain what device interfaces are and how to compare them at a basic level (wired vs wireless, purpose, compatibility).

Peripheral Interfaces (USB / Thunderbolt / Lightning)

Identify common peripheral connectors and describe typical use cases (USB-A/B/C, Thunderbolt, Lightning).

Networking Interfaces & Basic Tools

Identify common networking interfaces (RJ45, SFP/fiber, Bluetooth/NFC/RF/Wi-Fi) and basic tools (crimper, cable tester).

Display Ports & Display Sharing

Recognize common display connectors (VGA/DVI/HDMI/DP/USB-C) and basic display sharing concepts (mirroring/casting).

Common mistakes to avoid

Jumping into advanced certification depth instead of staying at Tech+ recognition level.

Choosing a related term without checking the exact device, service, or user need in the scenario.

Memorizing isolated definitions without connecting them to simple workplace examples.
