of AI is present in various segments of the economy; in industry, automation is a keynote for machines that keep getting smarter. With AI, the equipment manufactures and checks the products without having to be operated by a human, that is, it performs repetitive work and has no limitations for their use. Through the GPS (Global Positioning System), the routes suggested by online applications, generally, point out the best path, considering that the AI interprets data provided automatically by other users about the traffic on the roads. Online retailers, using online store algorithms, recognize user purchasing patterns to present offers according to their preferences. Financial institutions use AI algorithms to analyze market data, manage finances, and relate to their customers [33].
Thus, the first industrial revolutions created equipment that replaced manual labor, carrying out the work of many men with greater efficiency and less cost. Currently, in several cases, through the AI employee in tasks, they have been previously seen as “intellectuals”. In any case, the important thing is that AI theater is a reality. In this regard, the understanding of its mechanisms and the understanding of the possibilities that this provides must be expanded. The concept of AI refers to the creation of machines, not necessarily with physical bodies (software that can abstract, create, deduce, and learn ideas), with the ability to think and act like human beings and aim to facilitate everyday tasks [7, 34].
1.2.2 IoT Concept
IoT in the early days corresponded to the connection via the internet in physical objects, such as a toaster, especially sensors. Over the years, the concept of connecting the physical material world with the virtual world has evolved into a technological revolution in order to connect all the objects that people use on a daily basis to the internet (Figure 1.4), describing a scenario in which several things are connected and communicate, through technologies like Wi-Fi. The result is a smarter and more responsive planet [35, 36].
Figure 1.4 Internet of Things.
Thus, IoT currently matches a series of hardware that works connected to the internet, from a smart TV to a running watch that measures heart rate and sends this data to an application. However, it is possible to interpret what part of these devices uses, even on a small scale, AI. This technological innovation connects everyday items (smart devices), or smart sensors, to the internet, making the physical world increasingly closer to the digital. Thus, the technology describes the physical objects (things) connected and communicating (transmitting) with each other and with the user, transmitting data (information) to a network, as if it were a broad digital nervous system, i.e., a structure that allows the exchange of information (data) between two or more points [17, 18, 37].
Still pondering that every day, more appliances, watches, means of transport, and accessories are connected to the Internet and other devices, such as smartphones, tablets, and mobile devices that transmit signals and appear to each other. Still pondering that through a connected network, these devices can be connected via the internet with cars, refrigerators, microwaves, trains, airplanes, among other thousands of artifacts (Figure 1.5) [18].
The field of IoT practices has been diversified over time, and currently, the field of applicability and use of IoT is very broad, reflecting on numerous technological resources that have been used to provide connection of devices. Like Bluetooth technology, communication by proximity field (short-range wireless technology, which allows the exchange of information between devices with enabled and compatible NFC) is also a feature used in IoT. Making the devices “talk digitally” to each other, generating more productivity, comfort, information, knowledge, and practicality in general, and their uses and application can include health monitoring or leading real-time information about city traffic, or yet the number of parking lots available in parking, even indicating activities, reminders, or even content on their connected intelligent devices [38].
Nowadays, everyday “things” become intelligent and have their functions and role expanded by crossing data (information), seeing a virtual assistant crossing data from connected intelligent devices to inform, even if not requested, the time (travel duration) it will take to get to work when leaving the house, also relating the interconnectivity of smart IoT devices around the environment and making a digital assistant learn a user’s routine, their times, their location via GPS connection, the connection (link) to the car’s Bluetooth at a singular time (Figure 1.6), and the circumstance that this context has been repeated many times [18].

The IoT exchanges information is essentially derived from three elements that require to be associated with an application to work which are the intelligent devices, the network (structure), and a digital control system. The intelligent devices are all those imaginable equipped with sensors and antennas, among others, providing communication with the other elements such as lamps, bedside lamps, refrigerators, microwaves, cars, coffee makers, and watches, television, among others (Figure 1.7). The network is the means of communication such as Wi-Fi, Bluetooth, mobile data, and fiber optics, among others. The control system causes all data (information) captured from the devices (things) to be processed and then sent (transmitted) to a digital system that controls each aspect analyzed and evaluated [36, 39].
Big Data is the driving technology of IoT, related to data are currently the great creators and destroyers of business value. Since the IoT devices connected to the network are constantly sending, receiving, exchanging, and crossing data, i.e., constantly producing data. As a result, the accumulation, analysis, and use of Big Data are more significant, especially for companies, which have the most expressive production of data with IoT, as it has a large number of objects that can be connected or already connected. In addition, with data and information in hand, companies make fewer mistakes, produce more, and win more customers. To make sense (means of storing, tracking, analyzing, and making use of this large amount) of all this data (information), Big Data analysis has a fundamental role, which is critical for companies of all sizes [19, 40].

Still pondering the seven main attributes that define and differentiate a normal object or device from an item that is part of the great mass of IoT connectivity, these devices and systems include sensors that track and measure activity worldwide. Internet connectivity will be in the item itself (thing/device), probably collecting information over time through sensors, exchanging messages, and files with a Cloud platform. Like any computer, the devices will have some built-in processing power, even if only to analyze and transmit data. Although many of the IoT devices are not yet equipped with special features
