Technology has drastically changed the ways in which information can be stored, processed, retrieved, and transmitted. Modern technologies have made possible to send and receive information more reliably, quickly, and cheaply over long distances.

Large amounts of information are needed to operate modern societies, and generating, processing, and transferring information are among the most common occupations in modern countries. The spread of what it is now called “information technology” affects people’s ideas, beliefs, and attitudes, and influences their behavior.

Although many people use computers, telephones, and cell phones, and they benefit from the information they receive via audio, television, and internet systems, few people understand how these devices and systems work. This limits people's ability to make informed decisions in their daily lives and to appreciate the challenges, opportunities, and problems associated with these new technologies.

This website has been designed to help you understand the basic scientific ideas that guide the design and development of materials and devices for information technology. You will also have the opportunity to learn about the most common processes used to store, process, and transfer information.
