A convection oven is a normal oven. “Convection” means it radiates heat and it flows through the oven by convection currents - hot air rises and cold air falls. As opposed to a microwave oven.
You probably mean a fan-forced oven - they have been standard in the US since the early 1970s.
In spite of what the words “convection” and “oven” mean on their own, a “convection oven” refers to an oven with a fan to circulate the air. An air fryer is a small convection oven.
