Informatique, or computer science, is the study of computers and computational systems. It involves understanding how computers work, how they process information, and how they can be programmed to perform various tasks. This field encompasses both theoretical concepts and practical applications, including software development, data analysis, and network management. Informatique also covers areas such as artificial intelligence, machine learning, and cybersecurity. Professionals in this field, known as computer scientists or software engineers, design algorithms, create software applications, and ensure the security of computer systems. The knowledge gained in informatique is essential for innovation in technology and improving everyday life.
