Introduction to the Unix Cluster. Node: Organization

The UNIX system is composed of three major parts:

The Kernel	Manages the resources of whatever computer system it lives on---to keep track of disks, tapes, printers, terminals, communication lines, and any other devices.
The File System	Organizing structure for data. Perhaps the most important part of UNIX, the file system is a repository for data and provides the means of organizing the layout of data storage through a directory structure.
The Shell	Command interpreter. Although the shell is just a utility program and not properly part of the system, it is the part that the user sees. The Shell listens to your terminal and translates your requests into actions.
