1. Which of the following is an example of an internet of Things technology?
A- a thermostat that changes temperatures at two scheduled times
B- a smartwatch that tracks heart rate and displays the same in an application
C- a microwave with present time options for different types of foods
D- a children’s bank that mechanically sorts coins by size
my answer- b
2. Which of the following is an abstraction used by an internet of Things technology
A- a smart thermostat controls the temperature of the house by allowing the user to see all data and control all systems
B- a smart drier has sensors that stop the drier when no moisture is detected in the clothes
C- an application in a car provides exact coordinates for the cars location using latitude and longitude
D- a computer’s central processing unit controls the cooling of the computer system based on internal temperature
my answer- c
3. Explain a common effect of an abstraction.
A- it limits the controls a user has to several buttons
B- it provides a user with multiple of buttons
C- it prevents the user from accessing any data collected from the sensors
D- it provides a user with all the data collected by the sensors
my answer- a
4. Which of the following describes the open systems interconnection (OSI) model?
A- a conceptual model that documents the communication functions of a computing system
B- a technical model that documents the communication functions of a computing system
C- a conceptual model that characterizes and standardizes the communication functions of a computing system
D- a technical model that characterizes and standardizes the communication functions of a computing system
my answer- c
5. Explain a benefit found from the use of abstractions in the internet of things.
A- complex systems run faster when they are using abstractions, so they are more efficient
B- users can benefit from complex systems without needing to understand the technology
C- it is easier for engineers to build complex systems to solve modern challenges
D- users are exposed to complex technologies and will gain a greater technical understanding
my answer- d
