No other industry uses as many technical terms as in IT / ITK. What terms are used regularly in IT / ITK and what do they mean? Is there a special IoT vocabulary that you should know and need for a good understanding? We have compiled a list of the most important technical terms and explain their meaning.

Constrained Application ProtocolThe Constrained Application Protocol (CoAP) is a specialized web transfer protocol for use with constrained nodes and constrained networks in the Internet of Things. The protocol is designed for machine-to-machine (M2M) applications such as smart energy and building automation.German:Constrained Application Protocol (CoAP )Consumer Electronics Control (CEC)
Consumer Electronics ControlWikipediaController Area Network (CAN) bus (CAN bus)
CAN Bus - high quality technology for industry & productionA system integrations at the highest level are possible with CAN Bus. That is why the Controller Area Network is considered the de facto standard in industrial companies in various industries. In the automotive industry in particular, the numerous functions and possibilities of this fieldbus system are used. Rightly so: CAN Bus is a very powerful system that guarantees fast data exchange, easy use and low costs.
With such its possible to capture measurement data flexibly, control digital inputs and outputs, flexibly expand systems, internal error management, design production processes sustainably - all this and much more can be implemented quickly and easily with CAN Bus.German:Controller Area Network (CAN) Bus (CAN-Bus )decentalised

interoperabilityGerman:Interoperabilität KNX® (KNX)
KNX® is a (worldwide & free) standard system, which is used to interconnect specific smart home devicesKNX brings together over 400 brands and thus offers everything to install automation systems completely independently of the manufacturer. The approx. 7000 certified IoT develop can be individually combined and thus tailored precisely to the requirements of the users. Once installed, the various components and systems can be realigned and expanded at any time.
Last but not least, KNX systems are characterized by a high level of convenience and have been proven to reduce operating and energy costs.

Single and locally operating systemGerman:monolitisch MQ Telemetry Transport (MQTT)
MQTT is an open OASIS and ISO standard for interconnecting devices via publish-subscribeMQTT: What is QoS (Quality Of Service)? The Quality of Service (QoS) level is an agreement between the sender of a message and the receiver of a message that defines the guarantee of delivery for a specific message. There are 3 QoS levels in MQTT: QoS 0 (at most once): This service level guarantees a best-effort delivery. There is no guarantee of delivery. QoS 1 (at least once): This service level guarantees that a message is delivered at least one time (> 1) to the receiver. QoS 2 (exactly once): This level guarantees that each message is received only once by the intended recipients. QoS 2 is the safest and slowest quality of service level. MQTT: What is the Retain Flag? A retained message is a normal MQTT message with the retained flag set to true. The broker stores the last retained message and the corresponding QoS for that topic. Each client that subscribes to a topic pattern that matches the topic of the retained message receives the retained message immediately after they subscribe. The broker stores only one retained message per topic. MQTT: What is the Client ID? The client identifier (ClientId) identifies each MQTT client that connects to an MQTT broker. The broker uses the ClientID to identify the client and the current state of the client. Therefore, this ID should be unique per client and broker. MQTT: What is the Clean Session flag? The clean session flag tells the broker whether the client wants to establish a persistent session or not. In a persistent session (CleanSession = false), the broker stores all subscriptions for the client and all missed messages for the client that subscribed with a Quality of Service (QoS) level 1 or 2. If the session is not persistent (CleanSession = true), the broker does not store anything for the client and purges all information from any previous persistent session. MQTT: What is the Last Will and Testament (LWT)? In MQTT, you use the Last Will and Testament (LWT) feature to notify other clients about an ungracefully disconnected client. Each client can specify its last will message when it connects to a broker. The last will message is a normal MQTT message with a topic, retained message flag, QoS, and payload. The broker stores the message until it detects that the client has disconnected ungracefully. In response to the ungraceful disconnect, the broker sends the last-will message to all subscribed clients of the last-will message topic. MQTT: Where is my LWT topic? The LWT messages will always be sent to (prefix)/(domainName)/(machineName)/lwt topicMultiprotocol Label Switching (MPLS)

Zigbee® is an wireless protocol standard, which is used to interconnect specific smart home devicesMany wireless network systems in buildings are based on the ZigBee standard. And not by chance: ZigBee is one of the best-known standards of radio protocols & IoT adapters for smart buildings, embedded devices and the Internet of Things.
In addition to the low energy requirement, ZigBee impresses with its high flexibility and simple application. The participating IoT devices manage the network completely independently and communicate using IoT sensors and digital signals.
