Answer:
a) Allows wireless communication between devices over short distances
Explanation:
Bluetooth is a wireless technology that enables devices to communicate with each other over short distances, typically within a range of 10 to 100 meters. It is commonly used for connecting devices such as smartphones, headphones, keyboards, and speakers.
Bluetooth works by establishing a wireless connection between devices, allowing them to exchange data or stream audio without the need for cables. It is designed to be energy-efficient and is ideal for personal area networks (PANs).
Bluetooth is widely used for wireless communication in various applications, including file sharing, connecting accessories, and enabling hands-free functionality in vehicles, making it an essential part of modern mobile and computing devices.
