what is bluetooth

Bluetooth is a wireless technology standard that allows devices to communicate with each other without cables or wires over short distances. It was originally invented as an affordable wireless alternative to wired peripherals such as keyboards, headphones, speakers, and other devices. Bluetooth works similarly to WiFi and cellular networking, but its optimized to perform simpler tasks at a shorter range. Bluetooth devices must be paired before they can begin transferring information, and the process of pairing your devices will vary depending on the device you are connecting to. Bluetooth protocols simplify the discovery and setup of services between devices, and Bluetooth devices can advertise all of the services they provide. Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files) . Bluetooth technology allows devices to communicate with each other without cables or wires, and it relies on short-range radio frequency.
