Computer science is a study of data processing by means of specialized software utilizing algorithms to manipulate and store digital information. There are many branches and possible applications of computer science:

• programming languages theory and development (basic branch of computer science)
• software engineering (creation of computer programs using programming languages)
• algorithms (the oldest branch of computer science)
• computer system architecture and administration
• computer databases
• computer networks
• computer security and cryptography
• computer graphics and visualization (image processing, computational geometry and video games)
• scientific computing (application of mathematical models in science, e.g. physics or chemistry)
• artificial intelligence (aka AI, is closely related to robotic development)
• informatics (information processing and engineering of information systems, e.g. medical informatics)
• webmastering (designing, programming and publishing Internet services)
