The statement that accurately describes a computer's vent is:
- An opening that dissipates internally generated heat
A computer's vent is an essential component that allows for the dissipation of internally generated heat. It is designed to release hot air produced by the computer's components such as the CPU, GPU, and power supply. By expelling this heat, the vent helps to prevent overheating and ensures that the computer operates within a safe temperature range. Proper ventilation is crucial for maintaining the performance and longevity of a computer system.
