Shannon entropy - use to calculate the bit needed to encode a symbol

[Outrageous]

To encode a symbol in binary form, I need 3 bits ,and I have 6 symbols.
So I need 6*3=18 bits to encode "We are" into binary form. As shown in http://www.shannonentropy.netmark.pl/calculate
My question: 3 bits to encode one then I have to use 16 bits, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
How to encode"W" into _ _ _ ? The _ _ _ is filled by 1 or 0 .
3 bits is calculated from entropy And what is that relate to the entropy? Please help. Really appreciate.

You need less than 3 bits on average, as you do not use all 8 symbols you could encode with 3 bits. For example, you can choose one symbol and encode it with just two bits (this "blocks" two 3-bit-strings).

How to encode"W" into _ _ _ ?

That is completely your choice. Pick anything you like, just provide a table where you describe the encoded symbols.

I moved your thread to our homework section.

Thanks. Can you please give me some simple links to read? Please

I don't have links, but every textbook and a lot of websites should cover that.
