External modem requires a/an __________ to get powered on.
- A.
AC adapter
- B.
Ethernet adapter
- C.
DC adapter
- D.
Data cable
Correct Answer
A. AC adapterExplanation
An external modem requires an AC adapter to get powered on because it needs an external power source to function. AC adapters convert the alternating current from a wall outlet into the direct current needed to power the modem. This allows the modem to receive power and operate properly. Ethernet adapters, DC adapters, and data cables are not used to power on an external modem.Rate this question:

The output of a blue color wire in an SMPS is
- A.
-12v DC
- B.
13v DC
- C.
22v DC
- D.
23v DC
Correct Answer
A. -12v DCExplanation
The output of a blue color wire in an SMPS is -12v DC. This means that when the blue wire is connected to a device, it will provide a direct current (DC) voltage of -12 volts. The negative sign indicates that the voltage is negative relative to the reference point. This voltage level may be used to power specific components or circuits that require a -12v DC supply.Rate this question:

In a color monitor, 1 pixel is represented by ___________.
- A.
Triad
- B.
Nibble
- C.
Both (1) and (2)
- D.
Btye
Correct Answer
A. TriadExplanation
A triad is a group of three colors that are used to represent one pixel in a color monitor. Each color in the triad represents a different component of the pixel's color, such as red, green, and blue. By combining different intensities of these three colors, a wide range of colors can be displayed on the monitor. Therefore, the correct answer is triad.Rate this question:

In a DVD- ROM, tracks are placed ________ mm apart.
- A.
0.74
- B.
10
- C.
164
- D.
74
Correct Answer
A. 0.74Explanation
In a DVD-ROM, tracks are placed 0.74 mm apart. This distance between tracks is important because it allows the laser in the DVD-ROM drive to accurately read the data stored on the disc. If the tracks were too close together, the laser may accidentally read data from adjacent tracks, causing errors. Conversely, if the tracks were too far apart, the laser may not be able to read the data at all. Therefore, the spacing of 0.74 mm strikes a balance between data density and readability.Rate this question:

The output of red color wire in an SMPS is
- A.
+5v DC
- B.
+12v DC
- C.
-5v DC
- D.
-3.3v DC
Correct Answer
A. +5v DCExplanation
The output of the red color wire in an SMPS is +5v DC. This means that the red wire carries a direct current (DC) with a voltage of +5 volts. The SMPS (Switched-Mode Power Supply) is a type of power supply that converts AC voltage from the main power source to different DC voltages for various components in a device. In this case, the red wire provides a +5v DC output, which is commonly used to power certain components or peripherals in electronic devices.Rate this question:
