Final answer:
Binary or executable files are considered regular files, created by compiling source code into machine code for execution by a computer's CPU and distinguished from device or special files related to hardware or system interfaces.
Step-by-step explanation:
Binary or executable files are classified as regular files. In the context of operating systems that follow the Unix philosophy, such as Linux and Unix itself, all entities in the file system are considered files. These include regular files, like text documents and binaries, as well as device files and special files which are used to access hardware directly or facilitate communication between processes.
Executable files contain code that is run by the computer's CPU. They are created by compiling source code from a high-level programming language into machine code that the computer can execute directly. This distinguishes them from device or special files, which are used by the system to represent and communicate with various hardware components or provide system-level interfaces.
