What is Bluetooth?
Bluetooth is a short-range wireless technology that allows devices to connect and communicate with each other. It uses radio waves to exchange data over a relatively short distance, typically up to 10 meters (33 feet) for most devices. Here are some key points about Bluetooth:
- Wireless convenience: Bluetooth eliminates the need for cables, making it easier to connect devices like headphones, speakers, keyboards, and phones.
- Data exchange: It enables devices to share information, such as transferring files between phones or streaming music to wireless speakers.
- Low power consumption: Compared to other wireless technologies like Wi-Fi, Bluetooth is designed to be energy efficient, making it ideal for battery-powered devices.
- Simple pairing: Most Bluetooth devices are easy to pair with each other, often requiring a simple confirmation step.
