What is memory measured in? Please Pick 2
Correct Answer(s)
A. Megabytes
C. Gigabytes
Explanation
Memory is measured in units called bytes. Megabytes (MB) and gigabytes (GB) are both units of measurement for memory. Megabytes are smaller than gigabytes, with 1 gigabyte equaling 1,024 megabytes. Therefore, both megabytes and gigabytes are valid measurements for memory.
2.
What is the Central Processing Unit (CPU) known as? Please Pick 2
Correct Answer(s)
A. The brain of a computer
D. The heart of a computer
Explanation
The Central Processing Unit (CPU) is known as the brain and heart of a computer. It is responsible for executing instructions, performing calculations, and controlling the overall functioning of the computer. The CPU acts as the brain by processing and interpreting data, while also acting as the heart by coordinating and managing the different components of the computer system.
3.
What does RAM stand for?
Correct Answer
B. Random Access Memory
Explanation
RAM stands for Random Access Memory. This is a type of computer memory that allows data to be accessed in any random order, rather than sequentially. It is volatile memory, meaning that its contents are lost when the power is turned off. RAM is used by the computer to temporarily store data that is actively being used by the CPU, providing fast and temporary storage for programs and data.
4.
What is a Hard drive?
Correct Answer
D. It is used to store programs and is another type of memory
Explanation
A hard drive is a type of storage device used to store programs, files, and data on a computer. It is not located in the monitor or kept in a memory card. While it is a type of memory, it is specifically used for long-term storage and is different from the computer's random access memory (RAM) which is used for short-term storage.

What does the tower have inside it? Please Pick 2
Correct Answer(s)
B. Cooling system
C. Motherboard
Explanation
The tower of a computer typically houses various components that are essential for its functioning. One of these components is the cooling system, which is responsible for keeping the internal temperature of the computer within safe limits. The cooling system usually consists of fans and heat sinks that help dissipate heat generated by the other components. Another crucial component found inside the tower is the motherboard, which acts as the central hub connecting all the other hardware components such as the CPU, RAM, and storage devices. The motherboard provides the necessary communication and power connections for the computer to operate effectively.
6.
What are two output devices?
Correct Answer(s)
B. Monitor
C. Printer
Explanation
The question asks for two output devices. An output device is a peripheral device that receives data from a computer and displays or prints the processed information. The options given include keyboard, monitor, printer, and mouse. While a keyboard and mouse are input devices, not output devices, a monitor and printer are both examples of output devices. A monitor displays visual output, such as text, images, and videos, while a printer produces hard copies of documents or images. Therefore, the correct answer is monitor and printer.
7.
What are two input devices?
Correct Answer(s)
A. Keyboard
D. Mouse
Explanation
The question asks for two input devices. The options given are keyboard, monitor, printer, and mouse. Out of these options, keyboard and mouse are the correct answers. Both keyboard and mouse are commonly used input devices that allow users to interact with a computer system by inputting commands or data. The monitor and printer, on the other hand, are output devices that display or produce information respectively, and not input devices.
8.
What size can a graphic card come in? Please Pick 2
Correct Answer(s)
A. 64MB
B. 4GB
Explanation
A graphic card can come in different sizes depending on the amount of memory it has. The options given are 64MB, 4GB, 156GB, and 10MB. The correct answer is 64MB and 4GB. This means that a graphic card can come in sizes as small as 64MB and as large as 4GB. The size of the graphic card's memory is important as it determines its ability to handle and process graphics-intensive tasks.
9.
Sound cards translate _ _ _ _ _ _ _ data into analogue sounds.
Correct Answer(s)
Digital
Explanation
Sound cards are devices that convert digital data into analogue sounds. They receive digital signals from the computer and use digital-to-analogue converters (DACs) to convert the binary data into electrical signals that can be amplified and played through speakers or headphones. Therefore, the correct answer is "Digital" as it accurately describes the type of data that sound cards translate.
