A) Chip-and-pin technology
B) Augmented reality
C) Kiosk
D) Digital literacy

Accepted Answer

The app is likely using augmented reality to display the location of restaurants and shops in relation to the user's current location. Chip-and-pin technology, kiosks, and digital literacy are not relevant to this scenario.

Question 4

What technology can collect information to make decisions, reach conclusions, and combine information in new ways?
A) robotics
B) artificial intelligence (AI)
C) virtual reality (VR)

Question 7

If you want to become a digital citizen, you only have to buy a piece of technology.

Accepted Answer

Becoming a digital citizen involves more than just buying a piece of technology. It requires developing a set of skills, knowledge and responsible behavior when using technology to engage with society, communicate and consume information online.

Question 8

Embedded computers usually are small and have limited hardware but enhance the capabilities of everyday devices.

Accepted Answer

Embedded computers are designed to be small and often have limited hardware resources, but they are integrated into a larger system or device to enhance its functionality or add additional features. Examples of embedded computers include those found in cars, appliances, and medical devices.

Question 9

Jorge saw a computer named Watson on the game show Jeopardy and was surprised at how many answers Watson was able to get correct, especially because the math problems involved solving equations. Watson was using augmented reality to solve the problems.

Accepted Answer

The statement is incorrect. Watson was not using augmented reality to solve the problems on Jeopardy. It was using natural language processing, machine learning, and other AI technologies.

Question 10

Tameka is expecting a baby and her partner wants to make sure he can get her to the hospital on the day of delivery using the fastest route possible regardless of time of day. How should he decide which technology to use?
A) He should choose a product that uses natural language processing, so he can type in where he wants to go.
B) He should choose a digital assistant that guesses where he wants to go based on the date.
C) He should choose a navigation app with artificial intelligence that can provide information about preferred routes.
D) He should choose an app with augmented reality that displays points of interest as he drives.

Accepted Answer

A navigation app with artificial intelligence can analyze real-time traffic data and suggest the fastest route to the hospital regardless of the time of day. This would be the best option for Tameka's partner to ensure they arrive at the hospital quickly during labor. Natural language processing, digital assistants, and augmented reality are not as relevant to this specific use case.

Question 11

New cars use embedded computers to make driving safer.

Accepted Answer

New cars have embedded computers that provide advanced driver assistance systems (ADAS) to enhance safety, such as automatic emergency braking, lane departure warning, blind spot monitoring, and adaptive cruise control.

Question 12

How is a microprocessor different from an integrated circuit?
A) Microprocessors are the size of your thumb and integrated circuits are the size of your hand.
B) Microprocessors are faster, smaller and less expensive than integrated circuits.
C) Microprocessors control the flow of electrons and integrated circuits control the flow of protons.
D) Microprocessors include tape and disk storage whereas integrated circuits are part of an operating system.

Accepted Answer

Microprocessors are a type of integrated circuit, but they are specifically designed to serve as the central processing unit (CPU) of a computer or other electronic device. They are typically faster, smaller, and less expensive than other types of integrated circuits, which may serve as memory, input/output controllers, or other components in a system. None of the other answer choices accurately distinguish between microprocessors and integrated circuits.

Question 13

Which of the following technologies assists users that have a visual disability?
A) screen readers
B) colorful webpages
C) captioning software
D) on-screen keyboards

Accepted Answer

Question 15

Which option lists the computer components in order from oldest to newest?
A) integrated circuits, microprocessors, vacuum tubes, transistors, personal computers
B) transistors, vacuum tubes, integrated circuits, personal computers, microprocessors
C) vacuum tubes, transistors, integrated circuits, microprocessors, personal computers
D) microprocessors, vacuum tubes, transistors, personal computers, integrated circuits

Accepted Answer

Vacuum tubes were the first electronic components used in computers. They were replaced by transistors, which were smaller and more efficient. Transistors were then replaced by integrated circuits, which combined many transistors onto a single chip. Microprocessors were the next major development, and they are essentially entire computers on a single chip. Personal computers were then created using microprocessors as their central processing unit. Therefore, the correct order is vacuum tubes, transistors, integrated circuits, microprocessors, and personal computers.
