ITPEC IP April 2023 — Question 10 of 100
Bluetooth is a standard for short-range wireless communication between PCs and peripheral devices. It is commonly used for keyboards, mice, headsets, speakers, controllers, and data exchange. Devices discover and pair with one another and then use defined Bluetooth profiles for particular functions.

Why not others:
- (b) IEEE 1394, also known as FireWire, is a wired serial interface
- (c) PCI is an internal computer bus for connecting expansion devices
