• Computer science is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Computing science encompasses many branches; some emphasize the computation of specific results (such as computer graphics), while others (such as computational complexity theory) relate to properties of computational problems. Still others focus on implementing computations. For example, programming language theory studies approaches to describing a computation, while computer programming applies specific programming languages to craft a solution to concrete computational problems.
  
• Information Technology (IT) or Information and Communication Technology (ICT) concerns technology and other aspects of managing and processing information, especially in large organizations. IT employs the use of electronic computers, storage media, network administration, server maintenance, and computer software to secure, convert, store, protect, process, transmit, and retrieve information.
