I see very often people using term binaries in different context. What are binaries? Collection on binary files, installation files, .dll files or what? Or is it just an general term for some collection of files on disk?
Binary means composed of two pieces or two parts and may refer to different things in different worlds of Mathematical, Computing, Science and Others.
But, in Computing, Binary refers to :-
The word binaries is used as a set of files which are produced after compiling essentially the object code that runs on machines. (and virtual machines/runtimes in case of Java/.NET)
While there are other things like JPEG photo, MPEG video, Zip files etc. are also binary in the sense they are not text or ascii files, but word binaries (used in context of software development) doesn't include them.
