Why do computers and televisions have vents?

Answer 1

Electronics generate heat when the electrons are energizing the circuits. Some circuits require heat dissipation in order to extend their life span of usage.

Answer 2

Computers and televisions have vents to allow heat generated during operation to escape. This helps prevent overheating and ensures that the electronic components operate efficiently and reliably. Ventilation also helps prolong the lifespan of the devices.
