Final answer:
Bluetooth is a wireless technology that uses short-range radio frequency transmissions and allows rapid ad hoc device pairings.
Step-by-step explanation:
Bluetooth is a type of physical interface that is a wireless technology that uses short-range radio frequency (RF) transmissions and provides for rapid ad hoc device pairings. It allows devices such as headphones and cell phones to connect wirelessly, enabling tasks like answering phone calls without directly handling the phone.
Bluetooth is a wireless communication standard enabling short-range data exchange between devices. Operating on radio frequencies, it facilitates connectivity for various devices like smartphones, speakers, and wearables. Bluetooth simplifies file sharing, audio streaming, and peripheral connections without the need for cables. Advancements, such as Bluetooth Low Energy (BLE), enhance energy efficiency, making it widely used in IoT devices. Pairing and connecting devices are user-friendly processes, contributing to its ubiquity in modern technology.
