This volume is an instructor’s manual for the Sixth Edition of Operating-System Concepts by
AbrahamSilberschatz, Peter Baer Galvin, and Greg Gagne. It consists of answers to the exercises
in the parent text. In cases where the answer to a question involves a long program, algorithm
development, or an essay, no answer is given, but simply the keywords “No Answer” are added.

In this activity, you will first identify the optimal operating system to use in a
given situation. Next, you will analyze the operating system selection in a
scenario. Microsoft Official Curriculum (MOC), available to IT Academies at a discounted price, is professional courseware intended for IT professionals and developers who build, support, and implement solutions by using Microsoft products and technologies. MOC is designed to cover the topics that employers know are mission-critical in the real world.
First developed in 1969 by Ken Thompson and Dennis Ritchie of the Research Group at Bell Laboratories; incorporated features of other operating systems, especially MULTICS The third version was written in C, which was developed at Bell Labs specifically to support UNIX The most influential of the non-Bell Labs and non-AT&T UNIX development groups — University of California at Berkeley (Berkeley Software Distributions - BSD) 4BSD UNIX resulted from DARPA funding to develop a standard UNIX system for government use Developed for the VAX, 4.
32-bit preemptive multitasking operating system for Intel microprocessors Key goals for the system:
portability security POSIX compliance multiprocessor support extensibility international support compatibility with MS-DOS and MS-Windows applications
Uses a micro-kernel architecture Available in four versions, Professional, Server, Advanced Server, National Server New version – Windows 2003, is now available
Operating System Basics
.What is an Operating System
• Resource Manager
- Resource include: CPU, memory, disk, network - OS allocates and de-allocates these resources
• Virtual Machine
- provides an abstraction of a larger (or
