According to the Turkish scientist El-Biruni, who was born in Khwarezm in 973 in today's Uzbekistan and inspired scientists such as Newton, Toricelli, Copernicus, and Galileo who came after him, the pleasure of science, that is, the pleasure of researching truth, is among the highest pleasures. Acting with this motivation, this book has been prepared in order to contribute even a little bit on the path of science like ants, to present the studies done in different engineering fields in order to search for the truth, and to give an idea to the new young scientists. When the book chapters are examined, there are mostly studies that include engineering application examples in different occupational groups of computer technology and software. The authors are experts in their own fields, and the chapters they have prepared have been subject to editorial control and refereeing, and it has been decided to publish by making arrangements in line with the recommendations of the referees.
