    ¿Cuál es el nombre del siguiente dispositivo?

    • Cpu

    • Server

    • UPS

    • Hard drive

    Correct Answer
    A. UPS
    Explanation
    The correct answer is UPS. UPS stands for Uninterruptible Power Supply, which is a device that provides emergency power to a computer or other electrical equipment when the main power source fails. It acts as a backup power source, allowing the device to continue running or be shut down properly during a power outage, preventing data loss or damage to the equipment.

    • Descarga de energía segura

    • Descarga electrostática

    Correct Answer
    A. Descarga electrostática
    Explanation
    ESD significa descarga electrostática. La descarga electrostática es un fenómeno en el cual se produce una transferencia rápida de carga eléctrica entre dos objetos con diferentes niveles de carga. Esto puede ocurrir cuando hay una acumulación de electricidad estática en un objeto y se descarga repentinamente al entrar en contacto con otro objeto. Este fenómeno puede ser peligroso ya que puede dañar componentes electrónicos sensibles. Por lo tanto, es importante tomar precauciones para evitar la descarga electrostática en entornos donde se manipulan dispositivos electrónicos.
