Computer science and engineering is the most important field of engineering studies today. Computers are used extensively in every field of work to increase efficiency and accuracy. While early computers were large machines that took up entire rooms, computer technology has advanced rapidly over generations to produce smaller and more powerful computers. Today, computer science has applications in areas like agriculture, defense, medicine, sports, banking, transportation and more. It promises continued growth in fields like quantum computing, supercomputing, artificial intelligence and more. Computer science enhances the work and growth of other engineering fields as well.
