This handbook is designed to give new system administrators an understanding of concepts, processes and technologies that will aid in their professional development. 

While every information technology culture is specific to its parent organization, there are commonalities and system patterns that apply to all organizations and information technology flow functions. 

The Accidental SysAdmin Handbook, Second Edition looks at those commonalities and provides a general introduction to critical aspects associated with system administration. It further acts to provide definitions for common computer terms and acronyms.
