The title "computer scientist" encompasses a variety of jobs in which people work to design computers and to discover new applications for them. Their work often involves using theory, research, and scientific concepts to solve problems. A strong background in computer science, mathematics, or a similar scientific area is necessary to work in the field.

Computer usage has expanded dramatically due to the development of the Internet, faster processors, cheaper prices, and better user interfaces. As a result, computers can be found in homes, companies, and educational institutions. They are used for business, scientific, and artistic applications. These applications have become increasingly complex, requiring sophisticated software and very fast processors. Computer scientists create the software and hardware products and concepts that fuel this technological progress.

Some computer scientists choose to work with hardware and explore new chip designs or design and build internal components...
