Define OSI layers
There are 7 layers in OSI model to helps networking professionals in understanding information flow from one source to destination.
A conceptual framework used to describe the functions of a networking system.
Computing functions into a basic set of rules and requirements in order to make the data secure between different products and software
Characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software
Describe the importance of the Physical Layer in the OSI Model
It accepts a frame from the data link layer and converts it into bits
Accepts bits from physical medium and convert it into the frame
Disassembles actual transfer of information from source to destination only, in the form of bit stream
It is accept bits from the network link layer and convert it into frame
Select the two advantages of the IoT:
Cutting down waste
The ability to access information from anywhere at anytime
Wastes time and money
Slows down communication between devices

Which below is NOT true?
IoT is part of IR4.0
IoT is the same as IIoT
AI, Machine Learning, Big Data, Cloud Computing, is not part of IoT.
Industry 4.0 (I4.0) is the same as Industrial Revolution 4.0 (IR4.0)
What is the true facts between IR4.0 and I4.0?
IR4.0 is the major things that we've discussed generally in all industries.
I4.0 is mainly about the industrial technology.
I4.0 is part of IR4.0.
Industrial IoT (IIoT) is Part of I4.0

What is Arduino?
Open-source electronic prototyping platform enabling users to create interactive electronic objects
Is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
The Arduino hardware and software was designed for artists, designers, hobbyists, hackers, newbies, and anyone interested in creating interactive objects or environments
Is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse
What is Raspberry Pi?
Is a series of small single-board computers developed in the United Kingdom
Is a tiny and affordable computer that you can use to learn programming through fun, practical projects.
Is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse
Is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
Choose the TRUE statement for ESP8266 and ESP32 board.
The ESP32 and ESP8266 are cheap Wi-Fi modules perfectly suited for DIY projects in the Internet of Things (IoT) and Home Automation fields
Both chips have a 32-bit processor. The ESP32 is dual core 160MHz to 240MHz CPU whereas the ESP8266 is a single core processor that runs at 80MHz
The ESP8266 adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy compared to ESP32
The ESP8266 comes with touch sensitive pins that can be used to wake up the ESP8266 from deep sleep, a built-in hall effect sensor
What is MQTT?
Is a lightweight, publish-subscribe network protocol that transports messages between devices
Is a simple messaging protocol, designed for constrained devices with low-bandwidth
It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser
Is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network
Choose which electronic board below commonly used for IoT devices?
ESP32 / ESP8266 / Arduino
Raspberry Pi
Servo motor driver
Infrared module
What is IoT Platform?
an Internet of Things (IoT) platform is the support software that connects edge hardware, access points, and data networks to other parts of the value chain (which are generally the end-user applications)
IoT platforms typically handle ongoing management tasks and data visualization, which allow users to automate their environment.
IoT platforms are often referred to as middleware solutions, which are the “plumbing” of the IoT
None of above
Which below are the consumer products of IoT?
Google Home
Alexa
Philips Hue
Sonoff
Tuya
What is a smart Home ?
Household appliances so that they can be monitored and controlled from one central point.
An IOT system for the comfort and security of people.
Home that can talk and do all the works without command.
