Why do Bluetooth devices need pairing?
Show answer & explanation
Answer: Establishes secure connection
Saves battery power — Wrong. Pairing does prevent unnecessary connections that drain battery, but primary purpose is security—ensuring only trusted devices connect.
Establishes secure connection ✓ — Correct! Pairing creates a secure link between Bluetooth devices. During pairing, devices exchange encryption keys and store them. This prevents unauthorized devices from connecting and ensures data privacy. Without pairing, any nearby device could intercept your audio or data! Paired devices recognize each other automatically afterward. Security first!
Extends wireless range — Wrong. Pairing doesn't extend range. It creates authentication between devices so they securely recognize each other and prevent unauthorized access.
