IoT has taken over our lives. As you have come to this blog you already know about it.

Whether you are interested in smart homes, smart cities, cutting edge computing, or IIoT, We’ve compiled this tech glossary page with list of IoT devices, IoT protocols, and Internet Of Things – Centric phrases that you should know while you dive into our connected future. If we missed something, let us know in the comments and provide us with new terminologies and what should be a good definition. In a way its your dictionary.

IT being part of new era of devices with endless list of terms. Thus we showcase here only Glossary starting with alphabet “A”. Keep following our blog for updated list.

The Glossary of Terms – A


AAA meaning is its full form only i.e. Authentication, Authorization & Accounting.


AAL – Ambient Assisted Living

AAL are Intelligent systems that are to assist the elderly and others with care activities daily, mostly through IoT technology. Where application fields are mainly security (for example, observation), functionality (such as automated light switches), and entertainment.


ACaaS – Access Control as a Service

A recurring fee-based IoT system where a facility manager outsources electronic access control to a third party. Each facility need not maintain a dedicated server.


Acceleration Sensing

It’s a concept referring to the increase in movement of an object from one point to another that  should be along a straight line or axis. Typical application includes remote control, pointing devices, fitness monitoring equipment, gesture recognition etc.



A tool that measures changes in gravitational acceleration in the unit it may be installed in. Accelerometers are mainly used to measure acceleration, tilt or vibration in many devices.


Access Control

It’s a system that is to determine who, when, and where one (people) is allowed to enter or exit a facility or area. Door locks is the traditional form of access control, however modern access control may include electronic systems or wireless locks. Access control may also apply to cyber security.


Access Point

A Wi-Fi node that allows users entry to a network, typically a LAN.


Active Sensor

It’s a sensing device that mainly requires external source of power to operate.



A device that creates motion by converting electrical energy into mechanical energy in an electromechanical system. (An actuator can also stop motion by clamping or locking.) A dynamo as such is an example of actuator.


ADAS – Advanced Driver Assistance Systems

Digital features incorporated into vehicles to enhance driver safety and performance. ADAS functionality includes blind spot detection, digital vision for lane departure warnings, radar for collision avoidance, and Vehicle to vehicle (V2V) communication for multiple vehicles to operate near each other. The data and connectivity integral to ADAS transforms vehicles into IoT devices.


Additive Manufacturing

Industry-specific term for 3D printing, involves building products by adding layers instead of the traditional technique of removing material via milling.



The scope for an entity to be targeted and found. To be addressable, entity must be uniquely identifiable, meaning that it must be linked with something — typically an alpha-numeric string — and it should not be associated with anything else in that system.


AES – Advanced Encryption Standard

Electronic data encryption specification was established in year 2001. Concept operates on public/private key system. Planning for key management and implementation is important when setting AES. This is the standard protocol for setting transport layer security in IoT devices.


AIM – Automated Identification and Mobility Technologies

Group of technologies that are used to identify, store and to communicate data. For example –  barcoding. Though there are many technologies in this area which are used for different services or are often used in combination.


AML – Ambient Intelligence

An environment that is sensor-filled which not only interpret, react to human events but also  activity & learning to adapt over time. Operation of  environment and services change based on that activity.


AMPS – Advanced Mobile Phone System

Its an analogue based cellular mobile system using FDMA technology.


AQMP – Advanced Message Queuing Protocol

An open application layer protocol for message-oriented middle-ware with a focus on queuing, routing (P2P, PubSub), security, and reliability.

It’s an open-source standard works as application layer protocol for business message communications. Its features include message style, queuing, routing, stability, and security.


Android Wear

When an open-source platform extends the Android system to wearables with help of the SDK includes that includes an emulator too.


Anomaly Detection

Its a statistical technique that determines which patterns are normal and then examines items that don’t conform to those patterns. Unlike simple classification, in anomaly detection of data,  users don’t know what they are looking for.



Standard 41 – American National Standards Institute, Its for TDMA cellular.



Standard 41 – American National Standards Institute, Its for CDMA2000 cellular.



Standard 41 – American National Standards Institute, Its for control signal messaging on SS7.



Standard 41 – American National Standards Institute, its for CDMA cellular.


AP – Access Point (Wireless)

A Wi-Fi node that allows users entry to a network, typically a LAN.


API – Application Programming Interface .

It’s a set of commands and related protocols to interact with an operating system, device, or specific software part. In IoT, an API lets the developer access framework externally without going deep in software programming at server end. The functionality of a device or sensor can be accessed for reports or changed based on API permissions related to public or specific users.


Application Agents

Its helps to address the lack of overheads for an end-to-end, peer-to-peer networking in IoT architecture, this is achieved by their presence in propagator nodes in an enterprise. They move intelligent command data to the edge of the network, this is to help manage traffic, allow a real-time response to dynamic IoT conditions, and provide local client services.


Application Software

These are programs that enables specific, end-user actions. This means that software uses the potential provided by computers to become an application. Examples – Microsoft Word (i.e. for text editing), Adobe Photoshop (i.e. for image editing), and other programs.



A single-board micro-controller used for prototyping without having to deal with breadboards or soldering. The software that is used to operate an Arduino is absolutely free and open source.


ARP – Address Resolution Protocol.

It’s a communication protocol that is used to convert an IP address into a physical address. This way, computers can communicate with each other, despite only knowing each other’s IP addresses, by sending an ARP request that informs them about the other computer’s MAC address.


ASSN – Application Specific Sensor Nodes

Integrating sensors and sensor fusion in a single device. It has a built-in intelligence to overcome the complexity of using multiple sensors to a specific problem. Example – augmented reality, navigation, positioning, and more.


AT Commands

Attention commands, developed by Dennis Hayes, that are used to set data connections. The set of short string commands allow developers to set up calls with a modem, as well as perform far more complex tasks. For an example of an AT command set, take a look at Telit’s 3G module, the HE910, AT command directory.


Audio Profile

Hardware profile used with the Bluetooth applications that is to include custom AT commands and functionality is dedicated to wireless streaming of audio. Examples include A2DP, which allows streaming of audio to speakers. Where as, an audio gateway profile allows two-way audio communication used in devices like headsets.


Augmented Entity

A physical entity that is represented by virtual entity on digital level. An augmented entity combines the two and represents as an combination of the two entities.


AWS – Amazon Web Services

Brand Name given to collection of remote computing services which are offered by Amazon.com. In all it combines to make a cloud computing platform.  Services of AWS can not only be used for dedicated work but IoT too via IoT AWS.
