Formal Science, Computer Science
Computer science is the study of computation, information, and automated processes. It is concerned with how data is represented, processed, stored, communicated, and transformed by computer systems. The field examines both the theoretical foundations of computation and the practical design of hardware and software systems. Computer science includes the study of algorithms, programming languages, computer architecture, operating systems, databases, networking, artificial intelligence, cybersecurity, software engineering, and human computer interaction.
Computer science investigates what can be computed, how efficiently problems can be solved, and how computational systems can be designed to perform useful tasks reliably and accurately. Another major aspect of computer science is the practical construction of computing systems. This includes designing software applications, operating systems, compilers, distributed systems, databases, and network infrastructures. Computer scientists develop methods for creating reliable, secure, scalable, and efficient system platforms. The discipline also overlaps with electrical engineering in areas such as computer hardware design and digital systems.

Computer science differs from simple computer use or information technology. Using software applications, operating a computer, or maintaining information systems may involve technical skills, but computer science focuses on the underlying principles and mechanisms that make those technologies possible.
