The correct answer is I and II.
Here's the breakdown:
I. True – The Internet of Things (IoT) is indeed the network of devices that have the ability to connect and exchange data.
II. True – The IoT can increase our vulnerability to cyber attacks because more connected devices create more potential entry points for attackers.
III. False – While the IoT has many positive aspects, it also comes with negative consequences, such as privacy concerns, security vulnerabilities, and potential data breaches.
Thus, the options that are true are I and II.
