Thanks , leena for referral.

i am no IT expert,but what i could gather it is still helpful for those who are used to e- learning. 

SCORM is a set of technical standards for e-learning software products.SCORM tells programmers how to write their code so that it can “play well” with other e-learning software. Specifically, SCORM governs how online learning content and Learning Management Systems (LMSs) communicate with each other. SCORM does not speak to instructional design or any other pedagogical concern, it is purely a technical standard.

An example or analogy?

Let’s take DVDs for example. When you buy a new movie on DVD you don’t need to check to see if it works with your brand of DVD player. A regular DVD will play on a Toshiba the same as it will on a Panasonic. That’s because DVD movies are produced using a set of standards. Without these standards a studio releasing a new movie on DVD would have a big problem. They would need to make differently formatted DVDs for each brand of DVD player. This is how online learning used to be before SCORM was created.
