Preface

A few years ago we could basically pick and choose the job we wanted. If we were dissatisfied we moved on. Job mobility was the order of the day. Now, in far too many cases, outsourcing, downsizing, and/or rightsizing seem to be the order of the day. Job stability often appears to be little more than words found in a dictionary.

Here is a book that will enable you to beat out the competition . Your competition is all those people trying to get the same job you are trying to get. Let us face it, as far as you are concerned there is only one person that is going to get each job. As for the job you want, you want it to be you, not them. If you play your cards right, try as hard as you can, prepare yourself, and never give up, you will succeed. And this is what this book is all about preparing and succeeding.

There are numerous FAQs, questions and answers, articles on Web, books, etc. on the market covering almost every conceivable topic, however, from an interview perspective it is not feasible to brush up on all these materials when you may not have much time. With technologies evolving so rapidly, it is hard for even the most knowledgeable professional to handle job interview with confidence and precise answers to tough technical and management questions. This is especially true when it comes to information about such vital new areas of job opportunity as UNIX, Networking , etc. Here is a book that will enable you to ace any technical interview as it provides answers to challenging and difficult questions in a wide range of important areas. The key objective of this book is to cover all the core concepts and areas which all UNIX developers, designers , administrators, and architects should be familiar with to perform in their jobs or to do well in interviews. The interviewer can also use this book to ensure that they hire the right candidate depending on their requirements.

UNIX Questions and Answers is a one-stop reference that both beginning and experienced software engineers will use successfully in technical job interviews and countless on-the-job situations. Providing the answers to critical questions, from the simplest to the most advanced, this book is arranged to get you the information you need the moment you need it. You will find helpful explanations of crucial UNIX issues.

Packed with numerous real-life examples and case studies, UNIX Questions and Answers is an indispensable guide covering all the areas of UNIX . It is a practical and constantly usable resource for understanding fundamental UNIX issues and implementing workable solutions based on authors more than 30 years development and management experience.

There are in all about 30 0 questions with det ailed answers so you do not have to worry about spending countless hours browsing the Web or text books for correct answers that get you succeed. This book is not a multiple choice question and answer book as we believe we need to have detailed understanding of concepts and principles to better do our job as a software engineer , administrator, or architect . This book also does not contain any non-relevant material to avoid making it bulky.

Key topics covered include: UNIX Basics, UNIX Kernel, Utilities, File Structure and Directories, Shell Fundamentals, Shell Commands, Shell Programming, Shell Scripting, Threads and Processes, Commands, Networking, Sockets, Protocols, LAN, TCP/IP, System Administration, Network Administration , Managing UNIX Jobs, User Environment, Performance Tuning, Installation and Configuration, Glossary, Acronyms, Visual Editor, Makefile, s ed, a wk , Regular Expressions, Mail , Linux, etc.

In the latest edition, we have demonstrated a commitment to clear, direct writing, with questions that are quick, to the point and stress the core essentials of UNIX . Those who want to learn more about the profession, as well as those who want to fine-tune their development skills, will find it to be a straightforward question and answer format with hundreds of questions covering key UNIX knowledge areas. Whether you are a seasoned professional, novice, student, or instructor of UNIX , you will appreciate this book for its rich content and ability to test your skill and knowledge.

Simply return the book if you are not 100% satisfied - no questions asked. However, I would request you to please provide your valuable suggestions for improvement since I strongly believe in continuous improvement.

More than 2 00,000 copies of authors previous books have been sold. Please review authors profile at: http://books.basandra.com/aboutus.html

It is planned to keep this book updated on a regular basis so that the readers are kept current with latest trends .

Basandra Books introduced its first question and answer book in 2010 and, as the software engineering profession continues to mature, improvements to this book have evolved naturally from various feedbacks on the previous editions. I sincerely appreciate the invaluable feedback provided by various readers and reviewers.

All in all a lot of effort by the author has been put into providing you, the technical and management professional whose livelihood depends on the currency of his or her technical and management knowledge and skills, with as much new meaningful information as possible. If I am able to give you any of the information that you need to survive and succeed then my effort would be considered more than worthwhile.

A 32-bit OS runs on at least a 32-bit processor and generally makes a flat, 32-bit virtual address space available to programs. Programs running on a 32-bit OS will generally use 32 bits as their fundamental word size. For instance, an integer will be a 32-bit value rather than a 16-bit value. The term 32-bit OS has also come to imply a variety of technologies, such as preemptive multitasking and process isolation that are common to most 32-bit operating systems but not necessarily inherent to a 32-bit operating system.
