IoT – E Glossary Terms


IoT is now part of our all lives. You know about it thus you are here.

You are looking for smart homes, smart cities, IIoT, cutting edge computing etc. We’ve consolidated these IoT devices list, IoT protocols list, & Internet Of Things that you should be aware of while you jump into common connected future. If you find something missing then let us know in the comments or provide us any new terminologies with good definition. This IoT dictionary is yours.

IT is now the part of new era of numerous list of devices. We are indexing here only terms and devices that are starting with alphabet “E”. Keep following our blog for updated IoT list.


The Glossary of Terms – E

Embedded Device or Systems

It’s a computer with dedicated functions within a larger mechanical or electrical system; it is part embedded of a complete device.


Endpoint Device

It’s an Internet-capable device on TCP/IP network.



Or eHealth, telemedicine, telehealth and related to mHealth. This is support of medical processes & applications through information & computer technologies. It can also include the gathering & communication of data with automated responses of certain devices & processes.


EAN – European Article’s Number.

This is used to mark & identify products. Since 2009, it’s also called GTIN (Global Trade Item Number). The number is usually found beneath barcodes & consists of up to 13 digits (EAN 13 barcode).


Electronic Control Unit (ECU)

Also known as a node, an Electronic Control Unit is a device, such as a sensor or an actuator, that is connected to other device via CAN Bus. A vehicle can contain number of ECUs for functions such as power window, mirror adjustment, cruise control, airbags, entertainment, &, most significantly, engine control. Two or more ECUs are needed to form a CAN.


Embedded Device Hacking

This is type of hacking where vulnerabilities are exploited in embedded software to gain control of the device.


Embedded Firmware

The flash memory chip which stores specialized software in an embedded device to control its functions.


Embedded Software

Specialized programming in chip or on firmware in an embedded device to control its functions.


Embedded System Security

Reduction of vulnerabilities & protection against threats in software running on embedded devices.


Embrace, Extend, and Extinguish

A strategy that is associated with Microsoft to defeat open standards with proprietary extensions. Many IoT projects which are open source, so this strategy would be against open development.


EMI Protocol

It’s an extension to UCP (Universal Computer Protocol). It’s used to connect Short Message Service Centers that stores, transforms, and send short messages.


Energy-Harvesting Technologies

Technologies that use small amounts of energy transferred from close proximity to power small wireless devices. Applications related to it can be found in wireless sensor networks or wearable tech. While besides others energy sources are like sun, wind, or kinetic energy.


Enhanced Data rates for GSM Evolution (EDGE)

Its an enhancement to 2G GSM networks i.e. to improve data transfer speeds as well as provide downlink speeds of upto 1 Mbit/s & uplink speeds of upto 400 kbit/s. It builds on available GSM or GPRS standards & is thus easily integrated into existing network.


Edge Gateway

It’s the connecting factor between device analytics & cloud data processing & analytics


Edge Layer

It’s an architectural change in field of IoT that breaks the traditional norm of client-server model. This is first layer for connectivity for devices to connect and communicate to before going to the server. This is also responsible for local connectivity of devices & for managing the data collection & connection to this server.


Enterprise Mobile Duress (EMD)

These Systems are designed to detect personnel related emergencies within large facilities, like that of hospitals or campuses. Where determining physical location of persons in distress is critical issue. EMD systems are robust extension of Personal Emergency Response System (PERS) that are in the enterprise, focusing totally on the protection of people from emergency incidents like violence etc.


EPC Global

It’s a non profit organization founded by GS1 (i.e. former EAN International) & GS1 US (former UCC). It serves to spread, improve, & standardize the Radio Frequency Identification (RFID) technology & to support communication of gathered data through the Internet.



Electrostatic Discharge.

This discharge occurs when two electrical objects with different electrical charges come in close contact with each other. The difference created in charge is often due to friction. Sometimes, this short process is accompanied by sparks, like that can be seen with lightning. ESD may lead to severe damages to electrical devices (such as generators).



Electronic Serial Number (used in CDMA). Replaced by the MEID.


Ether CAT

A field-bus system developed by Beckhoff, which allows for real-time Ethernet. It helps to achieve short data updates, times accurate synchronization, & low hardware costs, so it can be used for automated or control systems. CAT here stands for Controller and Automation Technology.



Enhanced Voice-Data Only (also known as Enhanced Voice-Data Optimized).
