About the Flashcards
Flashcards for the CompTIA Network+ exam concentrate on the OSI reference model, guiding you through all seven layers from Physical to Application. Each card clarifies the name and purpose of every Protocol Data Unit-bit, frame, packet, and segment-and shows how addressing schemes and routing decisions shift as you move up the stack.
You'll match common protocols like TCP, HTTP, SSL/TLS, and ARP to their correct layers and learn which devices-hubs, switches, routers-operate where. Quick prompts reinforce the difference between connectionless and connection-oriented transport, the role of IP versus MAC addressing, and other terminology likely to appear on test day.
Topics covered in this flashcard deck:
- OSI model layers
- PDUs and data flow
- Layer-specific protocols
- Networking devices
- Addressing methods
