The instruction says to break the piece into blocks of 16KB and send the blocks in each request message  
I don’t quite understand what piece refers to here. It is the hash value or something else?

Hi @JavaIsNotHard, the file you want to download is divided into pieces, which in turn are divided into blocks—so each piece represents **a part of the file**.

Each piece is identified by an index. Our tester will specify which piece it wants your program to download:

Remember that your code already knows the `piece length`. For example, if the piece length is 160KB, your code will need to request 10 blocks to download the entire piece.
