The history of the application of computers to education is filled with broadly descriptive terms such as computer-managed instruction (CMI), and integrated learning systems (ILS), computer-based instruction (CBI), computer-assisted instruction (CAI), and computer-assisted learning (CAL). These terms describe drill-and-practice programs, more sophisticated tutorials, and more individualized instruction, respectively. The term is currently used to describe a number of different educational computer applications. FirstClass by SoftArc, used by the United Kingdom's Open University in the 1990s and 2000s to deliver online learning across Europe, was one of the earliest internet-based LMSs.
