A UAV (Unmanned Aerial Vehicle) is an aircraft that operates without a human pilot onboard. Instead, it is either remotely controlled by a human operator or programmed to fly autonomously using onboard computers and sensors. UAVs are commonly known as drones and are used in various fields such as surveillance, agriculture, delivery, photography, and military operations. Their ability to access hard-to-reach areas and perform tasks without risking human life makes them valuable tools, but they also raise cybersecurity and privacy concerns due to their potential for misuse.
