In the context of IoT devices, hardware can be classified into general devices and sensing

00:14.280 --> 00:18.840
devices. The general devices are the main components of the data hub and information

00:18.840 --> 00:24.160
exchange. They are connected either by wired or wireless interfaces. Home appliances are

00:24.160 --> 00:29.120
a classic example of such devices. The sensing devices, on the other hand, include sensors

00:29.120 --> 00:35.240
and actuators. They measure the temperature, humidity, light intensity, and other parameters.

00:35.240 --> 00:39.920
These IoT devices are connected to the network with the help of gateways. These gateways

00:39.920 --> 00:44.280
or processing nodes process the information collected from the sensors and transfer it

00:44.280 --> 00:49.480
to the cloud. The cloud access both the storage and processing unit. Actions are performed

00:49.480 --> 00:54.360
on the collected data for further learning and inferences. Wired and wireless interfaces

00:54.360 --> 01:01.480
like Wi-Fi, Bluetooth, Zigbee, GSMs, and so on are used to provide connectivity to

01:01.480 --> 01:06.880
ensure its ubiquity. Applications need to support a diverse set of devices and communication

01:06.880 --> 01:12.920
protocols from tiny sensors capable of sensing and reporting the desired factor to powerful

01:12.920 --> 01:16.840
back-end servers that are utilized for data analysis and knowledge extraction.
