Knowledge is the application of information to work activities that results in positive organizational or individual performance. Learning is a process for gaining expertise grounded in a relatively permanent change in behavior. Learning occurs when information is understood and remembered by an organization or individual. Communities encompass people performing the same or similar work activities. They develop informal networks through which they can seek answers to, tell stories, exchange experiences, invent new ways of doing things, conspire, debate, and develop shared memories as well as connections to their daily work environment.
Technology is the applied science of digital tools specifically the Internet phenomenon.
Internet technologies are both a medium and an environment providing the delivery and context of the other three experiences. The richest experiences encompass aspects of all four realms. Ideally, people integrate these realms. Practice and process often cross boundaries while technology seeks to bridge the gaps. For example, as people converse, information is exchanged, understanding is shaped, and conceptual anchors are set.
