### IoT Conceptualization  
The Internet is a set of computers connected by a network, which is based on a series of protocols in order to interconnect multiple computers or mobiles worldwide in order to transmit services and information [8]. The Internet of Things is a combination of physical and electronic things that offers the ability of physical things to collect and exchange data. The Internet of Things is also considered to be of great importance in the field of wireless communications, so the foundation of this field is the ubiquity of the diversity of things, such as computers, mobile phones, sensors, and labels designed to interact with each other [9]. The Internet of Things works because of fundamental components such as devices, sensors, connectivity, data processing, and last but not least, interfaces. Thus, devices or sensors support the process of collecting environmental data, which can have various complexities [10]. They have a reduced capacity to store data, to pass data on, or to calculate, so that they have the ability to collect data, which is the final stage in the information process. Devices are usually connected to the internet for data attachment. Subsequently, the data are transferred to a cloud infrastructure, and in this case, by means of transport and communication, the sensors are usually connected to the cloud, such as satellite networks, Bluetooth, Wi-Fi, WAN networks, and many other examples [11]. After the data collection process in the cloud, the data are processed by software that is included in an interface and made available to users so that they have access to the IoT system. In data processing and management, the software consists of back-end data, a front-end user, and a B2B (business-to-business) interface. Usually, \"things\" are reported as devices, which can take various forms and have various uses, which make applications connect to the Internet in multiple ways. Experts are increasingly discussing the difference between IoT (Internet of Things) and IoE (Internet of Everything) [12], so they are considered to be two sides of the same coin. In other words, if the Internet of Things focuses on what physical objects are, the concept of the Internet of Everything is based on four important factors, such as the following: things, people, processes, and last but not least, objects [13]. The Internet of Everything has the ability to store data about people or processes, resulting in a number of applications, such as ERP. Organizations, the educational environment, and entrepreneurship are the ones that use IoT data in order to save a number of time-related costs or to generate new ventures [14]. Moreover, the future is determined by IoT technologies in which physical and digital things are connected and information is communicated through services and applications. The Internet of Things is the interconnectivity of promoting technologies, being an industrial revolution. It is aimed at devices that are part of the physical system that access the Internet. Things are equipped with built-in technologies through which they can interact with the outside world. At the same time, the IoE is concerned with things, people, data, or processes, making connections before turning information into business [15], which creates new opportunities in economics and business. The IoT dataset is meant to reduce acquisition costs, and data analysis is used to examine small or large datasets to make relevant conclusions about the prospects that can be acquired. IoT is facing a number of challenges in terms of security issues, so IoT technologies are shaping up around private and open exchanges. In terms of privacy, issues related to identifying a person from various public or private organizations are concentrated on the Internet. One of the most important IoT applications is smart cities. To increase efficiency, it uses ICT for better operability, to exchange information, and to improve the quality of services and the well-being of users [16].
