4. Conector utilizado para conectar a una PC a una red de computadora.

Conector RJ 45.

Conector RJ 11.

Conector RG 45.

Conector BNC.

The correct answer is "Conector RJ 45" because it is the connector commonly used to connect a PC to a computer network. The RJ 45 connector is specifically designed for Ethernet connections and is widely used in networking applications. It has eight pins and is capable of transmitting data at high speeds. The other options, RJ 11, RG 45, and BNC, are not typically used for connecting a PC to a computer network.

5. 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.

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.

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

True

False

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.

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

True

False

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.

8. Programa informático que tiene como fin específicamente recolectar y robar los datos de un sistema informático.

Virus.

Troyano.

Spyware.

Gusano.

Spyware is a type of malicious software that is specifically designed to collect and steal data from a computer system. Unlike viruses, trojans, and worms, which may have other purposes such as causing damage or spreading themselves, spyware focuses solely on gathering sensitive information without the user's knowledge or consent. Therefore, spyware is the correct answer in this case.

9. Dispositivo de almacenamiento que se caracteriza por que la escritura de la información en este se realiza en forma de espiral.

Disco Duro.

Disco Compacto.

Memoria Flash.

Memoria USB.

The correct answer is "Disco Compacto" because it is a storage device that is characterized by the information being written in a spiral form. This is a common feature of compact discs, where the data is stored in a continuous spiral track on the disc's surface.
