3)     What do you mean by IoT?

4)     Communication Security in IoT.

What is a System?

“A system is usually defined as the typical arrangement in which all its particular units get assembled and work together according to the given set of defined rules and regulations.”

In simple terms, we can define a System as the effective way of organizing, working, or doing one or more tasks according to the given fixed plan of action. As in the example of the Watch, that is a time displaying system, and generally, it follows the set of rules to display the exact time for the day effectively. If any parts of the Watch get destroyed or fail, the Watch will stop doing its work (it will not display the correct time). From this, it is concluded that all the components are interrelated; if one fails, the entire system will stop working.

What do you mean by embedded system?

The meaning of "Embedded" means something that is attached to another part of the things effectively.

Moreover, the embedded system can be defined as the respective computer hardware system in which the software is embedded effectively. An embedded system can be considered a kind of independent system or can be defined as part of a large system. 

The embedded system can generally be a microcontroller or microprocessor-based system defined to perform a specific task effectively. The best example of the embedded system is the "fire alarm” that can effectively sense smoke.

Components of Embedded Systems:

Generally, the embedded system consists of the three basic components that are as follows:

·        Usually consist of the hardware.

·        Usually consist of the application software.

·        Combination of the RTOS (Real-Time Operating System).

Characteristics of the Embedded Systems

The various characteristics of the effective embedded system are as follows:

·        Singly-functioned: One of the most important characteristics of the embedded system is that they are quite singly-functioned, which means it usually performs the specialized operations and effectively does the same things repeatedly.

·       Real-time as well Reactive: Another most important advantage of the embedded system is that they are quite real-time and reactive, which means many embedded systems usually react to the changes continuously in the respective system environment. They also compute the results in the respective real-time without any further delay.

Advantages:

The various advantages of the embedded system are as follows:

·        Embedded systems can be customized very easily and effectively.

·        The power consumption in the respective embedded system is quite low.

·        The very biggest advantage of the embedded system is that its costs are low.

Disadvantages:

The various disadvantages of the embedded system are as follows:

·        In the embedded system, the usual efforts for development are quite high.

·       The biggest disadvantage for the embedded system is that it takes more time to be gets marketed (to make an established position in the respective market).

What do you mean by IoT?

IoT usually stands for "Internet of things". In general, the internet of things usually describes the network of the many physical objects, which means the "things" that are quite embedded with the respective sensors, many software, and many other technologies that can be used to connect as well as the exchanging of the data with the respective devices and the respective systems all over the internet.

Moreover, these respective devices can vary from ordinary household objects to the most sophisticated industrial tools. In today's world, more than 7 billion devices are usually connected to the internet and effectively provide useful services to communities

Technologies that have made IoT Possible:

The various technologies that have made the IoT possible are as follows:

·        Good Connectivity.

·        Access to low-cost, low-power sensor technology.

·        Platforms related to effective cloud computing.

·        Analytics and the Machine Learning.

·        And many more etc.

Communication Security in IoT

Now moving on to discussing communication security. In general, the effective devices and networks that are usually connected over the internet of things are protected with the help of enhanced IoT security.

IoT Security

The effective techniques that are employed to protect internet-connected devices or network-based devices effectively are termed to be IoT security.

It was known that the internet is quite wide in range to perform effective communication, which could be quite threatening. This communication cab is made effective and secured with the help of IoT security.

Hence, providing effective and efficient communication over the internet.
