The PC Components Quiz! Trivia Test

1. What happened if the computer does not switch on?

RAM broken

Sound Card broken

Power supply problem

The VGA cable problem

Socket is not working

If the computer does not switch on, it is likely due to a power supply problem. The power supply is responsible for providing electricity to all the components of the computer, and if it is not functioning properly, the computer will not receive the necessary power to turn on. This could be caused by a faulty power supply unit or issues with the power source itself. It is important to check the power supply and ensure it is working correctly in order to resolve the issue.

2. What does the Video adapter do on a Computer?

Card gives more colours to your computer

Play video to your computer

Change colour from your computer

Display image onto your monitor

Makes video looking good

The video adapter is responsible for displaying images onto the monitor. It connects the computer's graphics card to the monitor and converts the digital signals from the graphics card into analog signals that the monitor can understand. Without a video adapter, the computer would not be able to display any images or videos on the monitor.

3. What does an Optical drive do?

Clean DVDs and CDs

Make copy of DVDs and CDs

Read DVDs and CDs

Control the speed of DVDs and CDs

Play CDs and DVDs

An optical drive is a device that is used to read DVDs and CDs. It does not clean or make copies of DVDs and CDs, nor does it control the speed of DVDs and CDs. Its primary function is to read the data stored on DVDs and CDs, allowing users to access and play the content on these discs.

4. A computer program is described as having 8-bit color. How many colors can it display?

8

16

64

128

256

An 8-bit color computer program can display 256 colors. This is because 8 bits can represent 2^8 (2 raised to the power of 8) different values, which is equal to 256. Each bit can have two possible values (0 or 1), and with 8 bits, there are a total of 256 possible combinations. Each combination represents a different color, allowing the program to display a total of 256 colors.

5. What is the Maximum memory that Hard Drive can have?

500GB Hard Drive

250GB Hard Drive

670GB Hard Drive

2X 500GB Hard Drive

50000MB Hard Drive

The maximum memory that a hard drive can have is not determined by the size of the individual hard drives, but rather by the capacity of the system or computer that the hard drives are connected to. Therefore, the correct answer of "2X 500GB Hard Drive" does not provide any information about the maximum memory that a hard drive can have.

6. The power supply in a computer is there to:

Increase the voltage to make computer faster

Enable the computer to work at a safe 240 volts ac

Reduce the voltage from 240V dc to about 12 V ac

To provide a very stable low voltage

Speedy tricks

The power supply in a computer is responsible for reducing the voltage from 240V DC to about 12V AC. This is necessary because the components in a computer require lower voltages to operate safely and efficiently. By converting the high voltage from the main power source to a lower voltage, the power supply ensures that the computer receives a stable and appropriate level of power.

7. It is not a good idea to open up a hard disk drive. This is because:

Dust could get in and cause a head crash

Data could escape

The hard disk runs in a vacuum and would run slower if there is air

Air molecules could react with the data to corrupt it

Its going to get dirty

Opening up a hard disk drive would introduce air into the system, which is not ideal because hard disks are designed to operate in a vacuum. The presence of air would create resistance and cause the disk to run slower, affecting its performance.

8. Which has the largest storage capacity?

USB Hard drive

USB Flash drive

Micro Disk drive

PCMCIA Flash

Memory Stick

The USB Flash drive has the largest storage capacity among the given options. Flash drives are known for their compact size and high storage capabilities. They can store large amounts of data, ranging from a few gigabytes to several terabytes, depending on the specific model. USB hard drives, micro disk drives, PCMCIA flash, and memory sticks also have storage capacities, but they are generally smaller compared to USB Flash drives.
