SCO UNIX Internals class
________________________
This intensive and unique 5 day course presents a detailed insight into
SCO's implementation of UNIX System V.3 on the Intel i80386 and i80486
architectures.
The course is targetted at experienced systems developers and technical
support staff who will benefit from an understanding of the complex
algorithms, data structures, and software and hardware interfaces within
the UNIX kernel.
The theory is reinforced with several carefully designed tutorial and
practical sessions, where students will be encouraged to use system tools
and to develop programs to explore the operation of the major functional
components of the operating system, including the filesystem, the process
scheduling algorithm, and the page fault handler.
Course Pre-requisites
_____________________
Fluency in the C programming language, including the use of pointers and
bitwise operations. Familiarity with some of the important system data
structures (the process table, the inode table, etc). An understanding
of Operating System concepts and a genuine interest in learning about
complex software and hardware issues.
