In the 1990s, the term Information and Communication Technology (ICT) was more widely used to replace IT – which is to give a greater emphasis on communication aspect. TYPES OF TECHNOLOGY #1) Communication Technology - refers to all equipment and programs that are used to process and communicate information. TYPES OF TECHNOLOGY #2) Content Technology - refers to a variety of devices and touchpoints that delivers and markets relevant, meaningful, and timely information. TYPES OF TECHNOLOGY #3) Computer Technology - this comprises of the available technology that are used in solving complex problems. DATA VS. INFORMATION Data are also known as raw facts, and is considered as the backbone of everything we do. Information – are data that has been interpreted so that it has meaning for the user. IMPORTANCE OF ICT The development of ICT has introduced four powerful worldwide changes that have altered the business environment.
