adj (used of a device) designed so that a property (as e.g. light) can be varied

Adjective variables are used to describe things that are easy to change, such as weather, interest rates, teachers' moods.

If you refer noun variables to people with phobias of mathematics, you may have a nightmare because they do not like to think about numbers or values ​​that can be changed in the equation . Variants of adjectives began to exist in the latter half of the 13th century, first applied to people, then applied to the weather in the late 15th century. The noun form first appeared in Lacroix differential integral calculation in 1816 and guarantees that math students solve the variable x for future generations.

A variable whose value determines a dependent variable or a variable in an expression (f (x) = y, where x is an independent variable)

In the case of starting devices such as switches, plugs, lights, thermostats, these take the form of lack of success, longer delay than usual, some successful commands (such as thermostat to raise the temperature, not essential temperature) I will take it. Verified, or completely wrong setting. Without these improvements, the product will reach the end of that work cycle in advance. Cause of the death of the IoT device; from the execution of the local software to the failure of the device, or the physical degradation of the device may be due to a failure of the connecting service.

We live in an interconnected world where smart devices connect to the Internet world. These devices are around us and always make decisions. Just like our thermostat, curtains and lights. As these devices are growing rapidly, according to a recent report, there is a possibility to live in the world of more than 20 billion smart devices connected to the Internet by 2020. Well, the three things I have done so far - the evolution from organic to inorganic (computer programs are more effective in making humans create AI), collective intelligence (billions connected through the Internet Smart device), and connect the expected number of devices - In order to become the next level of development, one artificial intelligence machine may not be smarter than the human brain. If all the smart devices in a smart device form part of an organism, its collective intelligence is far superior to the human brain.
