Question 1

The correct answer is: c: Hotkey

Question 2

The correct answer is: a: True

RAM is much faster than a hard disk that has physical limitations, such as rotation speed. In fact, it is 20-100 times faster, depending on the type of hardware.

Question 3

The correct answer is: a: True

Every digital device has RAM, including desktop computers, laptops, tablets, mobile phones, and IoT digital devices. It is not possible to run a computer without RAM as every computer system needs RAM to send instructions to the CPU.

Question 4

The correct answer is: d: You should keep three copies of your data, use two different storage devices, and store at least one of the backup copies offsite.

Question 5

The correct answer is: d: Keyboard

Since a keyboard has no storage of its own, it cannot be used to back up data.

Options A, B, and C are examples of storage devices that could be used to back up data.

Question 6

The correct answer is: a: A system administrator

System administrators often use them when managing hundreds or thousands of systems to easily adjust configurations for a large group of systems at once. This type of user interface is not suitable for inexperienced users who do not know how to use the different commands.

Question 7

The correct answer is: b: Receive

An output device is any physical hardware device that receives incoming data from a digital device and outputs it to the user.

Question 8

The correct answer is: a: BMP

The BMP file format is often used when sending images for professional printing or for assessment so that they can be kept the same quality, helping them pass the quality test.

Question 9

The correct answer is: c: JPEG and PNG

Question 10

The correct answer is: b: The maximum practical cable length is quite short.

Although there is no official maximum length, the maximum practical length of USB 3.0 is only 3 metres. Going beyond 3 metres will result in signal degradation and a slower speed.

Question 11

The correct answer is: d: Open-source software

This type of software is often collaborative, meaning that any user can take part in the development of it, making the total number of possible contributors unlimited.

Question 12

The correct answer is: a: QR code

Question 13

The correct answer is: c: It is more suitable for entering complex data.

Compared to automated data processing, it is much more suitable for entering complex data. Manual data can handle any data type. Data can be complex and automated entry methods may not exist for that data.

Question 14

The correct answer is: b: They are harder to share with other people.

Hard copies are harder to share than soft copies as they need to be posted or physically handed to other people.

Question 15

The correct answer is: b: False

Due to all the graphical elements, it requires more processing power and memory to run. This can cause issues with older systems that have limited memory and processing power.

Question 16

The correct answer is: c: It poses challenges in terms of legal requirements around data storage, processing, and transfer.

Question 17

Question 24

The correct answer is: c: RAW

Question 25

The correct answer is: a: Lossy compression

Lossy compression permanently deletes certain bits of data to reduce the file size. This process is irreversible, meaning that the file cannot be decompressed to restore it to its original form. Lossy compression is most commonly used for video, audio, and image compression, where removing some redundant and unneeded data bits has little to no perceptible effect on the representation and quality of the content.
