Question 1

________ is a two-dimensional code that can store much more information than ________.

Accepted Answer

A QR code can store much more information than traditional bar codes due to its two-dimensional structure, allowing for a larger amount of data to be encoded.

Question 2

You want to be able to track the pencils in your store because they seem to be disappearing. You would want to mark the pencils with ________.

Accepted Answer

Passive RFID codes are suitable for tracking items like pencils in a store as they do not require a power source and can be read by RFID readers to track inventory efficiently.

Question 3

Donald and his tech team are working on creating a new smartphone. They want companies to know be able to use location data to market to customers. Which feature of mobility are they concerned with?

Accepted Answer

Localization is the feature concerned with using location data to market to customers, as it involves tailoring content and services to the user's geographical location.

Question 4

Susan takes her car to the gas station and taps her phone to the gas pump in order to pay. Susan is using ___________.

Accepted Answer

Susan is using a mobile wallet, which allows users to make payments by tapping their phone to a payment terminal, utilizing technologies such as NFC (Near Field Communication).

Question 5

Marco fixes heating and air conditioning systems. While working on a current repair he gets information about where his next job is located and details about how to contact the customer and advise them about his arrival. Marco is using __________.

Accepted Answer

Intrabusiness applications are used within a business to improve efficiency and communication. Marco using an application to get information about his next job and contact details for the customer is an example of using intrabusiness applications to streamline work processes and improve service delivery.

Question 6

Donald and his tech team are working on creating a new smartphone. They want users to have the ability to connect to the internet. Which feature of mobility are they concerned with?

Accepted Answer

Connectivity is the feature of mobility that allows devices to connect to the internet or other networks, which is what Donald and his tech team are focusing on by wanting users to have internet access on their new smartphone.

Question 7

________ does NOT have an important role in the Internet of Things.

Accepted Answer

IPv4 does not have an important role in the Internet of Things (IoT) due to its limited address space, which cannot accommodate the vast number of devices in IoT networks. IoT devices often require IPv6 for its virtually unlimited address space.

Question 8

________ use internal batteries for power, and they broadcast radio waves to a reader.

Accepted Answer

Active RFID tags use internal batteries for power and can broadcast radio waves to a reader, allowing for longer range communication compared to passive tags, which do not have their own power source.

Question 9

________ rely entirely on readers for their power, are less expensive, and can be read only up to 20 feet.

Accepted Answer

Passive RFID codes rely entirely on readers for their power, making them less expensive, and they have a limited read range, typically up to 20 feet.

Question 10

The adoption of ________ has been an important factor in the development of the Internet of Things.

Accepted Answer

IPv6 has been crucial for the development of the Internet of Things (IoT) due to its ability to provide a vastly larger number of IP addresses compared to IPv4, accommodating the massive growth in internet-connected devices.

Question 11

_________ is a system in which any object, natural or manmade, has a unique identity and is able to send and receive information over a network without human interaction.

Accepted Answer

The IoT, or Internet of Things, refers to the system where objects have unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Question 12

Paul is travelling to a new client and he receives messages about traffic along the way. Paul is using _______.

Accepted Answer

Location services provide real-time traffic updates, which would be useful for Paul while traveling to a new client.

Question 13

_________ allows manufacturers to attach tags with antennas and computer chips on goods and then track their movement through radio signals.

Accepted Answer

RFID (Radio-Frequency Identification) technology involves using tags with antennas and computer chips that can be attached to items. These tags can then be tracked through radio signals, allowing for the monitoring of the movement of goods.

Question 14

Which of the following is FALSE of QR codes?

Accepted Answer

QR codes are not inherently larger than bar codes because they store information both horizontally and vertically. The size of a QR code can vary and is dependent on the amount of information it contains, not the orientation of data storage. QR codes are designed to efficiently use space in both dimensions, which allows them to store a significant amount of information in a relatively small area.

Question 15

Donald and his tech team are working on creating a new smartphone. They want users to have the ability to set individual messages and ringtones. Which feature of mobility are they concerned with?

Accepted Answer

The ability for users to set individual messages and ringtones on a smartphone is related to customization. This feature allows users to personalize their device according to their preferences.

Question 16

Marc leaves a store in the mall and sets off the alarm. This is because the cashier likely left the ___________ on the item Marc purchased.

Accepted Answer

RFID tags are used for security and inventory purposes in retail stores. If not deactivated or removed at the point of sale, they can trigger alarms when exiting the store.

Question 17

RFID was developed to replace ________.

Accepted Answer

RFID (Radio Frequency Identification) was developed to replace bar codes as it allows for non-contact reading and can store more information than a barcode, improving efficiency in tracking and inventory management. NFC (Near Field Communication), QR codes, and UWB (Ultra-Wideband) serve different purposes or were developed after RFID for different applications.

Question 18

________ is an autonomous device that monitors its own condition as well as physical and environmental conditions around it; it is an underlying technology of ________.

Accepted Answer

A wireless sensor is an autonomous device that monitors its own condition as well as physical and environmental conditions around it, and it is an underlying technology of the Internet of Things (IoT).

Question 19

The find my iphone app uses _________ to locate a user's device.

Accepted Answer

The Find My iPhone app uses telemetry, which involves the collection and analysis of data from remote or inaccessible points and its transmission to receiving equipment for monitoring. In this context, it refers to the technology used to track the location of the iPhone through GPS and other location services.

Question 20

When shopping in the supermarket, Arianna notices that the cashier swipes each of the boxes of cookies she is buying over a scanning device and the scanner reads what is printed on the box, the price is recorded and added to her bill. The boxes of cookies have _________ that make this possible,

Accepted Answer

Bar codes are used on product packaging to encode information such as price and product identification, which can be read by scanning devices at checkout counters in supermarkets. This allows for efficient and accurate billing.
