PREFACE

The aim of the OGO Cyber Assessment Book is to provide quality resources that will serve as a benchmark for students to attain requisite knowledge and skills in developmentally apposite ways. The book will also help in fostering social skills, a strong sense of self-worth, and an optimistic approach towards learning. This book endeavours to elevate the computer skills of the 21st century students. The theoretical as well as practical aspects of the subject have been simplified for a better understanding. This will help them to keep pace with time and face any competition. The book has been logically divided into chapters for the enhancement of interpretation. Each chapter contains MCQs based on the related topics. The questions are based on the six levels of understanding as given in Bloom’s Taxonomy viz. Knowledge, Comprehension, Application, Analysis, Synthesis and Evaluation which help in the development of the cognitive faculty of a student. The questions based on HOTS–Higher Order Thinking Skills, given at the end of each chapter encourage students to “think out of the box”. The Mock Test Papers prepare students attempt the questions in the same format as in the actual examination and making them adept at problem solving. The answers of the MCQs, HOTS and Mock Test Papers have been incorporated at the end of the book. The book is a fruition of sincere efforts and research by our authors and the editorial team. It will be our constant endeavour to make this book more valuable. We solicit feedback and suggestions from the users of this book for further improvement. —Publishers
