    Si la fuente de alimentación de una PC sobrepasa el voltaje normal (Máx. 12 v), ¿qué ocasiona?

    • Mayor rapidez de sistema .

    • Cheque dieléctrico.

    • Corto circuito.

    • Corto modulatorio.

    Correct Answer
    A. Corto circuito.
    Explanation
    If the power supply of a PC exceeds the normal voltage (Max. 12v), it can cause a short circuit. A short circuit occurs when there is an unintended connection between two points in an electrical circuit, resulting in a flow of current that is higher than what the circuit is designed to handle. This can lead to damage to the components of the PC and potentially cause it to malfunction or stop working altogether.

    Circuito impreso en el cual se incertan la mayoria de los componentes internos de la PC.

    • Placa Madre

    • Placa de componentes internos

    • Circuito integrado

    Correct Answer
    A. Placa Madre
    Explanation
    The correct answer is "Placa Madre" (Motherboard). The given statement describes a printed circuit board (circuito impreso) that houses most of the internal components of a PC. The motherboard is the main circuit board in a computer that connects all the hardware components together and allows them to communicate with each other. It provides the electrical connections and pathways for data transfer, power distribution, and control signals between the different components, making it an essential part of a computer system.

    El puerto usado por el mouse para comunicarse con la CPU es el DB25.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. The port used by the mouse to communicate with the CPU is not the DB25. The DB25 port is a serial port commonly used for connecting printers and other devices, but not for connecting a mouse. The mouse typically uses a different type of port, such as a PS/2 port or a USB port, to communicate with the CPU.

    Si una PC no enciende, en PRIMER LUGAR hay que revisar que el Sistema Operativo este activo.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement suggests that if a PC does not turn on, the first thing to check is whether the operating system is active. However, this is not correct. When a PC does not turn on, the first thing to check should be the power supply, connections, and hardware components. The operating system being active or not is irrelevant if the PC does not even start up.

The Administrador de Tareas (Task Manager) allows users to monitor and control running processes, performance, and system resources. The Administrador de dispositivos (Device Manager) is used to manage and troubleshoot hardware devices connected to the computer. These tools are essential for maintaining the system's efficiency and functionality.
