BLUETOOTH

Bluetooth is a wireless technology that lets devices connect and communicate without cables.

📡 Simple meaning

Bluetooth is like a short-range invisible wire in the air that connects devices such as:

• 📱 Phone ↔️ Earphones
• 🎧 Speaker ↔️ Phone
• 💻 Laptop ↔️ Mouse/keyboard
• 🎤 Microphone ↔️ Camera or phone

⚙️ How it works (easy explanation)

• It uses radio waves (2.4 GHz frequency)
• Devices “pair” with each other (connect)
• Once paired, they can send audio, files, or control signals
• Works only within short distance (about 10–30 meters depending on device) (Intel)

👍 Why people use Bluetooth

• 🚫 No cables needed
• 🔋 Uses low battery power
• 📲 Easy to connect devices
• 🎧 Common for wireless audio (earbuds, speakers)

📌 Example in real life

When you connect wireless earbuds to your phone, Bluetooth is what:

1. Finds the earbuds
2. Connects them (“pairing”)
3. Sends music from phone → earbuds
