The book "Elements of Technology" aims to help the student understand the processes and interdependencies of various technical systems, providing the basic technological knowledge that covers the main areas of modern technology.

The knowledge of technology is presented in a simple way and combined with the necessary accuracy in technical terminology.

The understanding of the elements of technology is complemented and reinforced through the appropriate, colored diagrams that have been selected, the comprehensive tables, and the graded sequence of the book's content development.

The book was created to meet the teaching purposes of the course "Elements of Technology" for the first grade of the Vocational High School (EPAL).

The authors and editors of the book ensured that the subject matter was developed according to the level of students who are coming into contact with basic technology topics for the first time.

The material developed in the book is necessarily useful for the future technician, regardless of the specialty they decide to pursue.

The "glossary" at the end of the book will help trainees understand any difficult words and technical terms.
