Computer science is the study of how computers and computer systems work. It covers everything from the theoretical foundations of computing to the design and implementation of algorithms and software.
In addition, computer science also covers the study of human-computer interaction, including user interface design, information retrieval, and machine learning.
Computer science has many applications in diverse fields, such as business, engineering, health care, law, science, and social sciences. It is also used to create new computer systems.
Computer science has a long history dating back to the early days of computing. However, it has only recently become a well-defined field with a number of universities offering accredited degrees in computer science.
