In its purest form, computer science is the research and development of technology that solves specific problems. Computer science has brought the world smart phones, GPS systems, the gaming industry and tablet computing, along with technological developments that assist government, industry and medicine. In addition to creating new technology, computer scientists also make improvements to existing technology and study the ways computers can make our lives easier. As with any branch of science, computer scientists perform research that establishes new information. This research begins with known mathematical algorithms and computer theory, and strives to constantly redefine what technology can do for us. Computer science also addresses how existing technology can be used in ways previously undiscovered, creating applications that may be faster, simpler, more efficient or less costly.
