Correct Answer: (d) Collaborative Filtering
Solution:

Collaborative filtering is a recommendation system that creates a prediction based on a user's previous behaviours. It is a method of making automatic predictions about the interest of a user by collective preferences.

It is the most common technique used when it comes to building intelligent recommender systems. Most websites like Amazon, You Tube, and Netflix use collaborative filtering as a part of their sophisticated recommendation systems.

12. In the context of wearable technology, which of the following tasks is/are accomplished by wearable devices? [I.A.S. (Pre) 2019]

1. Location identification of a person

2. Sleep monitoring of a person

3. Assisting the hearing impaired person

Select the correct answer using the code given below:

Correct Answer: (d) 1, 2 and 3
Solution:

Wearable devices such as smart watches can identify location of a person by tracking GPS location. Smart watches and Fitbit devices can also monitor heart rate and sleeping pattern of a person.

For assisting the hearing impaired persons, hearing aid wearable devices are more common and older than smartwatches popular today.

13. In the context of emerging communication technologies, which one of the following terms best applies to the above scenario? [I.A.S. (Pre) 2018]

When the alarm of your smartphone rings in the morning, you wake up and tap it to stop the alarm which causes your geyser to be switched on automatically. The smart mirror in your bathroom shows the day's weather and also indicates the level of water in your overhead tank.

Correct Answer: (b) Internet of Things
Solution:

The Internet of Things (IoT) is an emerging topic of technical, social and economic significance. IoT is the network of physical objects - devices, home appliances, cars and trucks, industrial and utility components and other everyday objects embedded with electronics, soft-ware, sensors and network connectivity and powerful data analytic capabilities that promise to transform the way we work, live and play.

These devices can communicate and interact with others over the internet and they can be remotely monitored and controlled.

14. Which of the following technologies will be enabled by the 5G mobile communication networks? [69ᵗʰ B.P.S.C. (Pre) 2023]

1. Internet of Things

2. Edge Computing

3. Network Slicing

Select the correct answer using the codes given below.

Correct Answer: (d) 1, 2 and 3
Solution:

5G Technology stands for Fifth Generation, which is the next generation of wireless network technology, designed to broaden the reach of mobile technology beyond LTE's capabilities.

It is the most recent version of cellular technology. 5G is distinguished by three key characteristics: faster speeds, lower latency, and the ability to connect many devices at the same time.

5G unlocks the true potential of edge computing with its low latency and high bandwidth capabilities, 5G can help to reduce the time it takes for loT (Internet of Things) devices and edge servers to communicate with each other, enabling real-time processing of data at the edge.

Network slicing is another feature of 5G networks, which creates dedicated virtual networks for lot devices to provide better network performance and security.
