This work not only immerses the reader in the foundations of information theory, but also reveals its diverse aspects, which are of great importance in the modern world, where information has become a key resource. From the first pages, the book captures attention, inviting the reader to understand what information is, how it is measured and transmitted. The authors examine in detail the basic concepts, such as entropy, coding, data transmission and noise, as well as their practical application in various fields - from telecommunications to bioinformatics. The reader will be able to learn how these theoretical foundations are used to develop new technologies that change our lives, for example, in the field of the Internet, artificial intelligence and big data. This book will be of interest to both undergraduate and graduate students studying mathematics, computer science and engineering sciences, as well as professionals working in the field of information technology, communication and medicine .. It is suitable for those who seek to expand their knowledge of how information shapes our perception of the world and affects decision-making. If you are passionate about science, technology and want to understand how modern society works, “Information Theory” will be a real discovery for you. The topics raised in the book go beyond purely scientific research. The authors touch on the philosophical aspects of information, discuss its role in communication and interaction between people. In the context of information overload faced by modern society, the understanding of information theory becomes especially relevant. The book helps the reader not only to understand how information is formed and transmitted, but also to learn to critically comprehend it, which is an important skill in the era of fake news and manipulation. The style of the authors can be described as accessible and fascinating, which makes complex concepts understandable even for those who do not have deep knowledge in mathematics or computer science. Each section of the book is filled with real-life examples, making it easy for the reader to associate theory with practice.
