- [Instructor] The IoT has two main components:
hardware and software.
These components communicate
using a wide variety of protocols.
Hardware refers to the physical devices
that are used to collect and present data,
like sensors and actuators,
such as temperature, proximity,
pressure and human digi sensors.
Or hardware devices used to present data,
like desktop, computers, tablets and cell phones.
And human-machine interfaces for industrial applications.
Hardware also includes standard network devices,
like routers and switches,
as well as the devices used in the application layer
or backend applications,
such as monitoring, data processing,
smart traffic and personal healthcare devices.
IoT devices are capable of analog-to-digital conversion,
collection and generation of data,
remote connection, which means the ability
to be controlled over the internet,
real-time monitoring, and device safety
for data security.
The second component is software.
IoT software is the set of programs,
which enable data storage,
data processing, data transferring and data analysis.
Also provides data collection, data integration,
real-time analysis, optimization
and communication protocols.
IoT software also connects the hardware devices
that collect the data to the end user applications.
Also helps to transfer a task
from the application layer back to the devices,
so it works in both directions.
