How It Works
The KNOPPIX distribution has been optimized to run within RAM from the CD-ROM. It does not need
to modify the hard drive or install itself anywhere. It can be run without fear of damaging the current
contents of your hard drive.
Summary
This chapter briefly discussed the history of Unix and introduced some of the versions of Unix. The Unix
core components— the kernel, shells, file system, and utilities — were introduced.
In the past, Unix was considered a system geared to the most computer-savvy users and those who wanted
a system for core functionality, with no regard to aesthetics or user friendliness. Unix has evolved to fit the
needs of many different types of users, from the no-nonsense corporate environment to the novice com-
puter user’s desktop. There are rich desktop environments available for many flavors of Unix, for example,
and every currently selling Macintosh computer is running a version of Unix right out of the box.
In Chapter 2, you begin using a Unix system from initial login to logout.
