Communication structures refer to the layout of the existing communication groups and channels. We would like to introduce the four best known types of layouts: * Point to Point: this is the most straightforward. It only involves two participants. It may be ’simplex’, meaning that only one participant communicates (therefore the process is only a one-way process). It may be ’full-duplex’, which means that the communication partners can equally send information to each other (for example Skyp…

Communication is an activity which involves several parties (multi-party). The parties in these activities exchange information with each other. Communication activities must have at least two participants. In the background, its main purpose is always to exchange information. It always reflects the sender’s intention.

Mathematical set is the totality of well-defined objects. The objects which belong to the set are called the elements. This state of belonging to a given set is called relation, which has the following sign: a∈X You may read the given relation like this: “the elements of X set”, or “X set contains the following elements”.$$ Z = \{1, 2, 3, 4, 5, ...\} $$$$ A = \{1, 3, 5, 7, 9\} $$$$ A = \{x \mid x \text{ is an odd integer and } 1 \leq x < 10 \} $$

Information is one of the basic concepts of 20th-century science. According to our scientific physical world view, the material particles and objects in our world constantly exchange energy in the four-dimensional space-time continuum while their order changes.

What is science? According to the definition: Science is understood as a provable and fact-based system of the objective relationships between nature, society, and human thought. However, science is not only a set of theories stored in textbooks. It is a dynamic process of exploration and innovation that directly shapes technology, industry, and daily life. Science is the reason we can design sustainable energy systems, create AI-powered applications, or even send rockets into space.$n$\(n-1…

The main steps of the scientific method 1) Observation : this is the primary basis for any scientific method. If something cannot be observed, then it cannot be scientifically tested. Important note: this point only applies to the natural sciences. For example, if we would like to analyze a battle that occurred during World War II we cannot examine the task this way because it has already happened.
