3. What is the difference between voltage and current?

Voltage is a song whereas current is a dried fruit.

Voltage is power and current is the measure of electrostatic potential.

Voltage is needed to eluminate star signatures in telescopes whereas current is the presence of the same star signature.

All of the above.

The correct answer is that voltage is the measure of force required to push electrons through a circuit, while current is the measure of the flow of those electrons. This explanation accurately describes the difference between voltage and current in terms of their definitions and their roles in an electrical circuit. Voltage is the potential difference that causes the electrons to move, while current is the actual movement of the electrons.

7. There are four modes of operation in CPUs. Select two of them from the following list:

Real mode.

Safe mode.

Compatible mode.

Depache mode.

The correct answer is Real mode and Compatible mode. Real mode is a mode of operation in CPUs where the processor operates in a manner similar to older processors, allowing direct access to the computer's hardware. Compatible mode is a mode of operation in CPUs that allows the processor to run software designed for older processors, ensuring backward compatibility.

8. From the list below, select tools which are commonly found in a repair tool kit.

Flat head screwdriver.

Phillips head screwdriver.

Cross head screwdriver.

Torx screwdriver.

All of the above.

The correct answer includes the flat head screwdriver, Phillips head screwdriver, and Torx screwdriver. These tools are commonly found in a repair tool kit as they are frequently used for various types of screws. The flat head screwdriver has a flat, slotted tip and is used for screws with a single slot. The Phillips head screwdriver has a cross-shaped tip and is used for screws with a cross-shaped indentation. The Torx screwdriver has a star-shaped tip and is used for screws with a star-shaped indentation. These three types of screwdrivers cover a wide range of screw types commonly encountered in repairs.
