LON-CAPA is an e-learning platform, also known as a Course Management System (CMS) or Learning Management System (LMS). It possesses the standard features of many learning platforms, but it differs from traditional e-learning platforms in that its many web servers can communicate with each other. Consequently, the term LON-CAPA can also refer to the LON-CAPA network, i.e. the entire set of LON-CAPA web servers and the specific implementation of an internet protocol that connects these web servers. LON-CAPA can also refer to the LON-CAPA project, i.e. the core team of scientists and programmers that develop and maintain the LON-CAPA software.
