1.1: Introduction to Computer Science

Computer science is the study of computers and computational systems, focusing on the theory, design, and application of software and algorithms to solve problems. It involves a broad range of topics, from the theoretical principles of computation to the practical development of software, hardware, and artificial intelligence. The field applies principles from mathematics, engineering, and logic to design and build systems that process information and automate tasks.

The field of computer science (CS) is the study of computing, which includes all phenomena related to computers, such as the Internet. With foundations in engineering and mathematics, computer science focuses on studying algorithms. An algorithm is a sequence of precise instructions that enables computing. This includes components computers use to process information. By studying and applying algorithms, computer science creates applications and solutions that impact all areas of society. For example, computer science developed the programs that enable online shopping, texting with friends, streaming music, and other technological processes.
