The UNIX operating system consists of Regular Computer files. In addition there are listed file directory , symbolic link file, named pipe file, domain socket file, device file, and doors (computing) file.

There have been over a hundred types of UNIX operating systems developed over the years to accommodate different types of hardware. FreeBSD, MacOS X Server, Red Hat Linux, and AIX are all UNIX-based systems.
The 'file' command in Unix attempts to guess what type of file you are looking at by reading the first several sections of the file and comparing it to a list of known contents for files. It is a useful command if you just want to know what type of file something is without having to examine it yourself. The command is not perfect because it does not detect all types of files but it does a reasonable job of guessing. It is used because in Unix there are no file extension types to tell us what kind of file a given file might be; you have to look inside the file to tell how it might be used.
The Unix file contains which kinds of fields?
There is no the system file. There are many files necessary to create a working Unix system.
file types are the ."something" part of a file. They serve to separate and recognize the content of files. (it's most used by windows since unix-like systems use the bash command line (#!path/to/program) with file with no extensions
Unix commands
The host file in Unix is usually located in the /etc directory.
Unix is a text file, not a web browser. :)
