While William S. Davis & T.M. Rajkumar aren't going to win a Pulitzer for literature, they should @ the least get a honourable mention for Operating Systems A Systematic View (OSASV). They've guided the book from its inception in 1977 up to this, the 5th ed., in 2001. However, as it's now 2003, using this as a textbook, the book is behind in a few areas of modest concern, but not to a detrimental degree as the base concepts are still germane; & will remain so until radical changes occur in hardware & software design. Despite some neglect on the part of the authors in regard to Open Source, I have no compunctions giving this text a full 5 stars, if anything based upon its merits as a really solid introductory text that's properly geared towards its audience. Using clear, concise language that is appropriate for a mid-range level student--the jargon level isn't suitable for total newbies, but will likely alienate super-users--Davis & Rajkumar walk readers through the gorier details of Operating Systems (OS) & the hardware where these interfaces run. I say gorier as even savvy end-users may not appreciate the elegant, complicated dance between an OS & its machine. As I'm very much a kinaesthetic learner, I find textbooks somewhat frustrating; especially poorly worded books are next to useless. However, I can find happy medium w/good illustrations supplementing my tactical inclinations. Of course, when dealing w/machine cycles, I'm not able to manually work a CPU, pick up & tinker w/memory as it holds a program, etc. Ergo, I found the illustrations in OSASV combined w/the language highly informative & descriptive; especially in Part One dealing w/how the hardware actually interprets commands from the OS & vice-versa. Unfortunately, the text doesn't list who worked on these invaluable drawings, but he/she/they deserve a special mention for their incredible work. I think the degree of schizophrenia brought up by previous reviews is misplaced. Personally, I never noticed any sort of divide regarding technical explanations or a divergence from the pedagogy of the preface. Davis & Rajkumar clearly state, [...] This is not a theoretical text. It is aimed @ those who are interested in using (rather than designing) computers, operating systems, & networks. The intent is to show why operating systems are needed & what, @ a functional, black box level, they do (p xxix). OSASV is what it is--a good, basic, classification of major OS & their concepts. The text provides a relevant sampling approach to understand how, & what constitutes the leading OS flavours, & how the OSes interact w/the hardware. It is, so to speak, a catalogue, not a step-by-step methodical explanation of inclusive details--such as a developer or programmer might desire. Rather, OSASV, is devoted more to aid in familiarity w/who, what, when, where, how, & to what extent--Davis & Rajkumar admirably rise to this objective in my opinion. After a brief overview, Part One of OSASV jumps right into explaining what may seem prosaic to super-users, but is in fact, valuable fundamentals of how the OS controls hardware system resources. Part Two is massively informative in relation to what an OS is doing 'under the hood' so to speak--shell, Input/Output Control System (IOCS), Central Processor Unit (CPU) management, & memory management. @ this point, the reader is ready Part Three & Part Four where the authors employ their systematic view--read cataloguing--of the major OS families. Starting w/MS-DOS & continuing through to IBM Operating Systems /Job Control Language (OS/JCL), Davis & Rajkumar talk the reader through the basics of these major OSes. Finally, in Part Five, the writers follow up w/some rudimentary information relating to networking, briefly go over the aspects of Novell Netware & Windows 2000 Server w/in the networked environments, & close the entire section w/a solid discourse on the Internet--Internet Protocols (IP), Application Protocols, Domain Name
