IoT Glossary Terms – C


IoT is all over the world. You come here means you know about it.

Be it anything from smart homes, phones or cities, We’ve listed this tech based index page of IoT devices, protocols, & Internet Of Things – Centric phrases. If we missed anything then do let us know.

IT being endless list of terms. Thus, we a part of it is only listed here i.e. Index of alphabet “C”. Keep following for updated list.


The Glossary of Terms – C



Purpose-built lighter protocols that allows the “things” in term IoT to communicate & interchange. It’s Built for machine-to-machine communications. Efficient, extensible data frames which not only have an open-source structure but also private data fields with simple checksum.


Competing Consumers

A messaging pattern where lot of consumers get messages from a common source (i.e. queue), however each message is delivered individually to only one consumer.


Connected Devices

Components that creates the Internet of Things. Plenty have built-in sensors and/or actuators and acquire data to help users or other devices that make informed decisions and monitor or affect outside functions.


Connectivity Protection

It’s a part of Edge Layer that serves towards making it certain that device connectivity doesn’t fail even if there is a network failure or an unreliable connection.


Constrained Application Protocol (CoAP)

Its an application layer protocol that is used in resource-constrained devices which allows Internet connectivity as well as remote control.



Or the Cloud, its means cloud computing. The name “cloud” is derived from the fluffy cloud generally used in Visio-style network diagrams which is to represent a connection to the Internet.


Cloud Computing

“In the cloud” refers to network of remote servers which are hosted online that store, manage, as well as process data.

Why it is important: Cloud computing is very vital for large sets of data. It’s also great for those who do need disaster recovery, environment friendly way to store data, collaboration controls, and security.

It’s a way where information technology related (such as storage or applications) are separated from individual computer & are supplied via the Internet (or Intranet-based service) at user’s demand. The “as-a-Service” moniker is also sometimes used for cloud computing services, like Software-as-a-Service or Platform-as-a-Service, and Infrastructure-as-a-Service. The back-end for many IoT devices is generally delivered via the cloud.


Cloud Communications

Communication services that are being provided by third parties which can be accessed & used through Internet. Program like Skype is one of well-known cloud communications applications.


Cloud Orchestration

It’s an automated management system of a cloud. This mainly includes all services and systems which are part of cloud & flow of information.


Card Not Present (CNP)

Its a type of credit transaction in which the merchant do not see the actual card. CNP has potential for fraud However it is vital for newer services like contact less mobile payments.



Code Division Multiple Access. It’s a Digital cellular phone service, it has the method that separates multiple transmissions channels over limited frequency allocation by using Spread Spectrum techniques (this concept was invented & patented by Hedy Lamar).


Chief IoT Officer (CIoT)

One of CxO class of corporate officers, the CIoT is one who coordinates the integration of IoT systems into an enterprise. Successful CIoTs will generally break down silos in between disciplines like data analytics, big data, security and communications protocols, etc.


Class 1 Bluetooth

Offers greater data transfer distance (over 100m i.e. up to 1km) wirelessly by using high power consumption (i.e. 100 mW).


Class 2 Bluetooth

Short-range wireless data transmission (i.e. 10-20m) which has low power consumption i.e. 2.5 mW approx.


Communication Model

Communication models do try to capture, explain and simplify the communication and then model communication. It’s one of the oldest & most famous models, Shannon & Weaver Model, which was created in 1949.


Companion Device

In wearable industry, it’s a companion device that requires a parent device (like smartphone) to operate fully. The opposite would be standalone device which can do everything on its own. A companion wearable generally communicates via Bluetooth with the parent.


Connected Home

If devices in house work interactively & information to residents and is accessed via high-speed broadband, then it could be called as a connected home. This may mean like the refrigerator reports that it is almost empty milk or that TV reminds you of your doctor’s appointment as it automatically gets the information from doctor’s computer. This concept is similar to Smart Home.


Controller Area Network (CAN)

In automobiles, a CAN is what connects to Electronic Control Units (ECUs) by using a multi-master serial bus (i.e. the CAN bus) to control actuators and/or receive feedback from different sensors. ECUs can be different subsystems like airbags, transmissions, anti-lock brakes, or even engine control. The standard includes ISO 11898-1 & ISO 11898-2.


Corporate Owned, Personally Enabled (COPE)

It’s kind of a compromise that is around pure BYOD. In COPE devices allows the user to control much of their data on the device, however the enterprise still controls majority of security model.



Cortex-A refers to series of processors from an ARM which are equipped with ARMv7 & ARMv8 command sets. They are used for applications which require lot of processing power, mainly in the areas related to mobile handset (i.e. smartphones), computing, automotive, digital home, wireless infrastructure and enterprise.



Cortex-M is a family of micro-processors that are developed by ARM. Which are mainly used in micro-controllers. They range from the very cheapest M0 processor and up to the Cortex-M4 i.e. used mostly for digital signal control. They are used in automotive, gaming & intelligent consumer products.



A novel system for inventors as well as entrepreneurs to bypass traditional methods of funding like venture capital. It is done by raising small amounts from a large group of individual backers. This concept is made popular by sites like Kick-Starter, crowdfunding and can act as a pre-ordering system. This allows the project’s creator to reduce the risk by ganging into consumer popularity before even production begins.


Cyber-Physical Systems (CPS)

Systems that combine aspects of computer and mechanical. A smartphone that combines software, hardware, and related with a physical device. In general, many mobile or embedded technologies or devices can be said as Cyber-Physical Systems. Therefore, the applications are manifold. This system often includes some form of sensor that can transfer attributes from real world to digital sphere
