About the Book: Courses on Computer Concepts We cant neglect the fact that computer has become synonym of our life style. It will not be exaggerated if we say that there is no civilized life without computer. Keeping in view the importance of computer some states like U.P. have made the computer subject compulsory to take entry in Government Services. Some other states are also likely to announce it. In the states that have made computer science subject mandatory the course is decided by the competent authority. Keeping in view the demand of such course book we have published a book on the computer concepts. This book is named as Course on Computer Concepts. The book is strictly based on the latest syllabus and pattern laid by DOEACC. In this book we have covered all the topics like introduction of computer, MS Word, MS Excel, Presentation, spread sheets, MS Powerpoint, MS Access, Computer security, GUI based MS Dos, Window 7, XP, Internet etc. A Number of Sample Papers will Model Test Papers, MCQ and true-false related question given in the Book make us different and our product more valuable then the product of the same line available in the market. We hope this book will prove as boon to the aspirant.

Analyze data like a pro, even if you’re a beginner. Practical SQL is an approachable and fast-paced guide to SQL (Structured Query Language), the standard programming language for defining, organizing, and exploring data in relational databases. Anthony DeBarros, a journalist and data analyst, focuses on using SQL to find the story within your data. The examples and code use the open-source database PostgreSQL and its companion pgAdmin interface, and the concepts you learn will apply to most database management systems, including MySQL, Oracle, SQLite, and others.* You’ll first cover the fundamentals of databases and the SQL language, then build skills by analyzing data from real-world datasets such as US Census demographics, New York City taxi rides, and earthquakes from US Geological Survey. Each chapter includes exercises and examples that teach even those who have never programmed before all the tools necessary to build powerful databases and access information quickly and efficiently. You’ll learn how to: Create databases and related tables using your own data Aggregate, sort, and filter data to find patterns Use functions for basic math and advanced statistical operations Identify errors in data and clean them up Analyze spatial data with a geographic information system (PostGIS) Create advanced queries and automate tasks This updated second edition has been thoroughly revised to reflect the latest in SQL features, including additional advanced query techniques for wrangling data. This edition also has two new chapters: an expanded set of instructions on for setting up your system plus a chapter on using PostgreSQL with the popular JSON data interchange format. Learning SQL doesn’t have to be dry and complicated. Practical SQL delivers clear examples with an easy-to-follow approach to teach you the tools you need to build and manage your own databases. * Microsoft SQL Server employs a variant of the language called T-SQL, which is not covered by Practical SQL.

As hacker organizations surpass drug cartels in terms of revenue generation, it is clear that the good guys are doing something wrong in information security. Providing a simple foundational remedy for our security ills, Security De-Engineering: Solving the Problems in Information Risk Management is a definitive guide to the current problems impacting corporate information risk management. It explains what the problems are, how and why they have manifested, and outlines powerful solutions. Ian Tibble delves into more than a decade of experience working with close to 100 different Fortune 500s and multinationals to explain how a gradual erosion of skills has placed corporate information assets on a disastrous collision course with automated malware attacks and manual intrusions. Presenting a complete journal of hacking feats and how corporate networks can be compromised, the book covers the most critical aspects of corporate risk information risk management. Outlines six detrimental security changes that have occurred in the past decade Examines automated vulnerability scanners and rationalizes the differences between their perceived and actual value Considers security products—including intrusion detection, security incident event management, and identity management The book provides a rare glimpse at the untold stories of what goes on behind the closed doors of private corporations. It details the tools and products that are used, typical behavioral traits, and the two types of security experts that have existed since the mid-nineties—the hackers and the consultants that came later. Answering some of the most pressing questions about network penetration testing and cloud computing security, this book provides you with the understanding and tools needed to tackle today’s risk management issues as well as those on the horizon.

In the chapters in Part I of this textbook the author introduces the fundamental ideas of artificial intelligence and computational intelligence. In Part II he explains key AI methods such as search, evolutionary computing, logic-based reasoning, knowledge representation, rule-based systems, pattern recognition, neural networks, and cognitive architectures. Finally, in Part III, he expands the context to discuss theories of intelligence in philosophy and psychology, key applications of AI systems, and the likely future of artificial intelligence. A key feature of the author's approach is historical and biographical footnotes, stressing the multidisciplinary character of the field and its pioneers. The book is appropriate for advanced undergraduate and graduate courses in computer science, engineering, and other applied sciences, and the appendices offer short formal, mathematical models and notes to support the reader.
