11.2.1 - IoT Devices

These flashcards cover vocabulary and key concepts related to IoT devices and systems, focusing on their architecture, functionalities, and security aspects.

Hub/control system

A communications hub that facilitates wireless networking for IoT devices; includes a control system.

Headless device

An IoT device that has no terminal interface, such as a smart speaker or an app-controlled device.

Smart devices

IoT endpoints that perform functions like lighting, temperature control, or security.

Embedded system

A complete computer system designed for specific, dedicated functions.

Static environment

An environment that does not allow frequent changes, ideal for security but potentially difficult for management.

Internet of Things (IoT)

A global network of embedded systems in devices equipped with sensors, software, and connectivity.

Machine to machine (M2M) communication

Communication where IoT devices exchange data with each other and with traditional systems.

Physical Access Control System (PACS)

A network of monitored locks, alarms, and surveillance for controlling access to physical spaces.

Building Automation System (BAS)

A system that manages and controls building operations like HVAC, lighting, and security.

Programmable Logic Controllers (PLCs)

Devices used in BAS for automation, controlling subsystems based on input from sensors.
