To start with if you are curious what what the fragments are made of of any given torrent than make your own. Torrents come in all forms and sized depending on the file. In general most are in rar files and you can extract them to .iso or .bin files and several others. The two I listed are just for example. If you are truely wanting to know the stucture or what the fragments are, set up a network at your residence or where ever you like. You can start by a ftp program. Different programs but they work in the same manner. Ftp programs and bittorrent clients are good at transfering large files or any files for that reason. You can ftp what ever you want and then study or learn what the fragments are.
Now the next part for the 1's and 0's. Anything and everything on your pc comes back to this. Yes 1's and 0's can bve copyrighted if it is how a program is written as those 1's and 0's are what makes it what it is. Now for the 1 and 0 itself no it cant be copyrighted but what is done with those when it makes something can be.
Words from a sentence in general cant be copyrighted but however if that sentence is a company's slogan or similar it can be. But logically if i were talking to you in person and said something to due with someone sentance or slogan that may be copy righted is one thing, but if I were to run a buisness of some sort and use that saying to my advantage is another thing. The person with the sentance or slogan will not like it and more and likely pursue some kind of action.
The way laws are precieved is a real grey area as there are many nations, countries and bodies of government that make their own laws. Their are to many ways around things to even take a chance unless you have alot of money and are willing to fight for whatever reason or action you take.
Good luck with what ever you are doing and welcome to the forums. Just my thoughts.
