Learning Objects (LOs) are units of e-Learning content that can stand on their own and deliver a certain portion of knowledge independently. LOs are intended to be granular and reusable. This granularity often allows you to play with a LO as if it is a brick in a bigger knowledge structure. Or perhaps, another way to understand them is to say that a LO is one dish in a huge buffet dinner. The one dish can also be eaten independently and would satisfy some hunger.
