Wireless Technology Types Flashcards
CompTIA A+ 220-1202 (V15) Flashcards
| Front | Back |
| Bluetooth | For short range direct wireless connections between smart phones, computers, laptops and other devices |
| NFC | Often used for payments but can have other use cases. Requires proximity and line of site for devices to share data wirelessly. |
| RFID | Radio-Frequency Identification uses electromagnetic fields to automatically identify and track tags attached to objects without requiring line of sight. |
| Tethering | Connecting two devices using a physical cable in order to share a network or data connection between them |
| Wi-Fi | IEEE 802.11 wireless standard enabling high-speed data transfer between devices and networks over medium to long ranges. |
| Z-Wave | Proprietary wireless standard that creates a mesh of wireless devices for sharing information. Often used in home automation networks. |
| ZigBee | An open standard based on IEEE 802.15.4 PAN that creates a mesh of wireless devices for sharing information. Often used in home automation networks. |
About the Flashcards
Flashcards for the CompTIA A+ exam provide a quick-study guide to the most common short-range and personal-area networking technologies candidates must recognize. Each card breaks down how standards such as Bluetooth, NFC, and Wi-Fi operate, their ranges, security considerations, and typical use cases like mobile payments, tethering, or high-speed internet access.
The deck also compares mesh protocols including ZigBee and Z-Wave with identification systems like RFID, helping you distinguish frequency bands, topologies, and device roles found in modern home-automation and IoT scenarios. Use this set to reinforce terminology, spot exam-style nuances, and build confidence identifying the right technology for a given scenario.
Topics covered in this flashcard deck:
- Bluetooth & NFC
- Wi-Fi standards
- ZigBee & Z-Wave mesh
- RFID identification
- Tethering concepts
