------------------------------------------------------------------------
Audience
System programmers and support personnel. Prerequisites: Participants need
a knowledge of UNIX concepts and terminology and experience with UNIX user
commands, utilities, and facilities. Completing our "Introduction to Open
Systems" and "UNIX Basics for Users" will satisfy these requirements
------------------------------------------------------------------------
Objectives
* Develop a detailed understanding of the main functions and services UNIX
provides to users and applications * Identify major subsystems of the UNIX
SVR4 kernel and explain their implementation in terms of concepts,
algorithms and structures
------------------------------------------------------------------------

Benefits
You'll expand your knowledge of UNIX System V Release 4 (SRV4) subsystems
in this wide-ranging overview, which covers process management, file system
management, memory management, and I/O management. You'll review the
architecture, main algorithms, and data structure and flow of SVR4
kernel-and touch on performance, maintenance, and administrative issues.
The knowledge you gain will improve your ability to use, support, maintain
or service your UNIX system.
