Unfortunately, I am not familiar with that.  Let me change it to a x-seek and see if anyone else can help you.  But first, you have to be more specific with your question.  What do you want to know?

Wikipedia have a lot of info about the Intel 8051 chip.  I think you can start from there.

http://en.wikipedia.org/wiki/8051

What course is that?  I think the subject is quite board.  

is about programming n program something into the chip....electronic

You are talking about Assembly Language Programming then!  Do you have any background of assembly language at all?

Sorry I cannot help you either. I have no idea what it is.
