Do you know which components are essential in a PC? Do you think you can pass this quiz? There are five vital parts of a computer: the motherboard, the Central Processing Unit, Random Access Memory, the Graphics Processing Unit, and Solid State Drive or Hard Disk Drive. Take this quiz and put your knowledge of PC components to the test.

### The power supply in a computer is there to:

• A.

Increase the voltage to make computer faster

• B.

Enable the computer to work at a safe 240 volts ac

• C.

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

• D.

To provide a very stable low voltage

• E.

Speedy tricks

C. Reduce the voltage from 240V dc to about 12 V ac
Explanation
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.

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

• A.

8

• B.

16

• C.

64

• D.

128

• E.

256

E. 256
Explanation
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.

### What happened if the computer does not switch on?

• A.

RAM broken

• B.

Sound Card broken

• C.

Power supply problem

• D.

The VGA cable problem

• E.

Socket is not working

C. Power supply problem
Explanation
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.

### What is the Maximum memory that Hard Drive can have?

• A.

500GB Hard Drive

• B.

250GB Hard Drive

• C.

670GB Hard Drive

• D.

2X 500GB Hard Drive

• E.

50000MB Hard Drive

D. 2X 500GB Hard Drive
Explanation
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.

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

• A.

Dust could get in and cause a head crash

• B.

Data could escape

• C.

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

• D.

Air molecules could react with the data to corrupt it

• E.

Its going to get dirty

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

### What does the Video adapter do on a Computer?

• A.

Card gives more colours to your computer

• B.

• C.

• D.

• E.

Makes video looking good

D. Display image onto your monitor
Explanation
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.
