hia fellas

i jst finished with creating a project (for my summer training) titled "Error Detection and Correction using Hamming Code", i hope u know what it exactly is! During my presentation, one of my professors asked me a question. It was:

How can i send an image thru a network?

Well, I replied to it and said that it was an implementation of Steganography!(Jst a wild guess) and the errors that occur will be rectified by the algorithm itself. Hopefully, my teacher not knowing much abt it agreed to me.......

But, i really want to know now, that how n image is transmitted thru a network?? Is it converted into bit?How? or Is it already in terms of bits?

Pardon me if this is the wrong place for the question!!

thnx
