The aim of this book is to help the students develop programming and algorithm analysis skills simultaneously such that they are able to design programs with maximum efficiency. C language has been used in the book to permit the execution of basic data structures in a variety of ways. Key Features 1. Simple and easy-to-follow text 2. Wide coverage of topics 3. Programming examples for clarity 4. Summary and exercises at the end of each chapter to test your knowledge 5. Answers to selected exercises 6. University question papers with answers 7. Objective type questions for practice

The book Operating System is an insightful work that elaborates on fundamentals as well as advanced topics of the discipline. Keeping the needs of the students in mind, this book offers an in-depth coverage of concepts, design and functions of an operating system irrespective of the hardware used. With neat illustrations and examples and presentation of difficult concepts in the simplest form, the aim is to make the subject crystal clear to the students, and the book extremely student-friendly. The book caters to undergraduate students of most Indian universities, who would find the introductory and advanced discussions highly informative and enriching. Tailored as a guide for self-paced learning the book equips budding system programmers with the right knowledge and expertise. The topics covered include: Organization of the computer system; communication between processes; threads and multithreading models; scheduling criteria and algorithms; synchronization among cooperating processes; deadlock situation; memory management; virtual memory; I/O system; disk scheduling algorithms, disk management, swap-space management and RAID; file types, attributes and access methods; managing files, directories and disc space; security and protection in computers; UNIX and Linux operating systems; implementation of various OS concepts in Windows 2000; multiprocessor and distributed systems.

This book provides a comprehensive overview of this multi-disciplinary subject, which has interaction with other disciplines, such as mineralogy, petrology, structural geology, hydrogeology, seismic engineering, rock engineering, soil mechanics, geophysics, remote sensing (RS-GIS-GPS), environmental geology, etc.

The book has been developed to provide comprehensive and consistent coverage of both the concepts of data structures as well as implementation of these concepts using C programming. The book utilizes a systematic approach wherein each data structure is explained using examples followed by its implementation using a programming language. It begins with the introduction to data types. In this, an overview of various types of data structures is given and asymptotic notations, best case, worst case and average case time complexity is discussed. The book then focuses on the linear data structures such as arrays, stacks, queues and linked lists. In these units each concept is followed by its implementation and logic explanation part. The book then covers the non-linear data structures such as trees and graphs. These data structures are very well explained with the help of illustrative diagrams, examples and implementations. The text book then covers two important topics - hashing and file structures. While explaining the hashing - various hashing methods, and collision handling techniques are explained with necessary illustrations and examples. File structures are demonstrated by implementing sequential, index sequential and random file organization. Finally searching and sorting algorithms, their implementation and time complexities are discussed. The sorting and searching methods are illustrated systematically with the help of examples. The explanation in this book is in a very simple language along with clear and concise form which will help the students to have clear-cut understanding of the subject.

The book enumerates the concepts related to C programming language. The best way to learn any programming language is through examples. The book uses the same approach - each concept is followed by an appropriate example to understand the implementation of the learned concepts. The book begins with the basic components of a computer and their functions, concepts of hardware and software, types of software, compilers, interpreter, linkers and loaders, programming languages, flowcharts and algorithms. The book explains C program structure, data types, constants, variables, expressions, operators, I/O functions and control structures. It teaches you how to use arrays, strings, functions, pointers, files, structures, dynamic memory allocation, storage classes and command line arguments. It also explains the searching and sorting algorithms. Questions and answers at the end of each chapter help readers to revise the essential concepts covered in the chapter.
