Because it makes it very easy to abstract input, makes programming easier and makes writing drivers easier.
On some platforms (unix, for example) devices are handled as special files.
Some context might help. The closest thing I can think of is /dev/tty, which is a unix-style device name (in unix, printers, terminals, and the like are treated as files).
If they are a root level user they have access to just about everything.
No, of course not. For example processes, memory-pages, environment variables and semaphores are not treated as files.

The C header files are in the same place as other Unix and Unix-like systems: /usr/include if you installed the compiler.
Linux and Unix and their variants have several different ways of locating files. each of the below commands can be used to locate files.findlocatewheriswhich
There is no the system file. There are many files necessary to create a working Unix system.
For Unix systems that are only talking to other Unix systems NFS (Network File System) is the most popular. If you want to share Unix files with Windows systems, then Samba is one of the most popular ways to accomplish this.
Unix files do not rely on extensions, therefore there is no command to find them.
You can read the files from Unix school by download the program to a word format. Also, you can use Adobe reader as well to read the material.
Files in unix operating systems with a '.' character as the first character in the filename are hidden.
