Hey everyone:

I am extremely interested in binary. All things binary. And Especially in the binary composition of executables and other data.
I was wondering:
Is there any way to see this binary data? (i.e. See the binary composition of a .txt file? for instance)
I am very interested.
Thanks

P.S.
I already know the system (colunms of powers of two, 0 and 1, ect..) so I at least have limited understanding.
