Internet of Things

IoT

100

It is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices.

What is internet?

200

It describes physical objects (or groups of such objects) with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks.

What is The Internet of things (IoT)?

300

It is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.

What is Cloud computing?

400

It makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application.

What is Middleware?

500

It is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication.

What is IEEE 802.11?

Network types by spatial scope

100

It is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.

What is a local area network (LAN)?

200

It is a telecommunications network that extends over a large geographic area.

What is a wide area network (WAN)?

300

It is a computer network for interconnecting electronic devices within an individual person's workspace.

What is a personal area network (PAN)?

400

It is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.

What is a wireless LAN (WLAN)?

500

It is a wireless network of wearable computing devices.

What is a body area network (BAN)?

Network Protocols

100

It is a conceptual model that 'provides a common basis for the coordination of standards development for the purpose of systems interconnection'. In this model, the communications between a computing system are split into seven different abstraction layers.

What is The Open Systems Interconnection model (OSI model)?

200

This Internet protocol suite is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria.

What is TCP/IP?

300

In the seven-layer OSI model of computer networking, this is the layer most closely associated with the physical connection between devices. It provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the line code to use and similar low-level parameters.

What is the physical layer?

400

This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. It provides the functional and procedural means to transfer data between network entities and may also provide the means to detect and possibly correct errors that can occur in the physical layer.

What is the data link layer?

500

This layer is responsible for packet forwarding including routing through intermediate routers.

What is the network layer?

MQTT

100

It is a lightweight, publish-subscribe, machine to machine network protocol for Message queue service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth.

What is MQTT (Message Queue Telemetry Transport)?

200

It is a server that receives all messages from the clients and then routes the messages to the appropriate destination clients.

What is an MQTT broker?

300

It is any device that runs an MQTT library and connects to an MQTT broker over a network.

What is an MQTT client?

400

It is a named logical channel and it is also referred to as a channel or filter. The broker will send to the subscribers only the messages published to this channel to which they are subscribed.

What is a topic?

500

It is the clients that register to the broker as interested in specific types of messages.

What is a subscriber?

Miscellaneous

100

They are portions of the radio spectrum reserved internationally for industrial, scientific and medical (ISM) purposes, excluding applications in telecommunications.

What are the ISM radio bands?

200

Compared to Classic Bluetooth, it is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range

What is Bluetooth Low Energy?

300

It uses electromagnetic fields to automatically identify and track tags attached to objects.

What is Radio-frequency identification (RFID)?

400

This is one of the main protocols of the Internet protocol suite. It provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network.

What is the Transmission Control Protocol (TCP)?

500

It is one of the core communication protocols of the Internet protocol suite used to send messages (transported as datagrams in packets) to other hosts on an Internet Protocol (IP) network. Within an IP network, this protocol does not require prior communication to set up communication channels or data paths.

What is the User Datagram Protocol (UDP)?
