NoSQL databases are non-relational, open-source, distributed, schema-less, and cluster friendly databases. They are hugely popular today owing to their ability to scale out or scale horizontally and the adeptness at dealing with a rich variety of dаta: structured, semi-structured and unstructured data. They are malleable and flexible enough to accommodate sparse datasets, besides maintaining cost efficiency and availability. Developers are working with applications that create massive volumes of new, rapidly changing data types – structured, semi-structured, unstructured and polymorphic data. Applications that once served a finite audience are now delivered as services that must be always-on, accessible from many different devices and scaled globally to millions of users. Organizations are now turning to scale-out architectures using open source software, commodity servers and cloud computing instead of large monolithic servers and storage infrastructure. Increasingly being used in big data and real-time web applications are NoSQL databases. NoSQL are the “Not only SQL” databases, implying that they support SQL-like query languages, or sit alongside SQL databases in polyglot persistent architectures.

This book has been specifically designed to orient students for the technical interview in Operating System concepts. This book has been written to help students undertake a thorough and objective preparation. The contents have been carefully handpicked from authors’ experience and expertise developed by being either direct witness to the recruitment process, mentoring students in their colleges, myriad discussion with peers who are placement organizers in colleges, hours of studying discussions on the topics in social media, blogs and dedicated web sites, and so it is no wonder that the book is highly focused for interview preparation in OS. The book is organized into twelve chapters, covering major subject areas and each chapter covers a number of exercises along with the correct answers. The book requires a basic knowledge of operating systems. As we elucidate later in the book, operating systems conceptual MCQs and problem solving isn’t really suitable for wide-ranging of beginners–though many have succeeded to use it–so the book will presume that the readers of this book have already covered basic concepts with the notions of system calls, file handling, formulae, along with ‘C basics’ and so on.
