PrefaceThe compilat ion of this book Information and

Communication Technologies (ICT) was motivated by

the desire to provide a concise book which can benefit

students to understand the concepts of energy and

environment topics.

This textbook Information and Communication

Technologies (ICT) provides all the requirements of

the students, i.e. comprehensive coverage of theory,

fundamental concepts and objective type questions articulated in a lucid language. The concise

presentation will help the readers grasp the theory of this subject with clarity and apply them

with ease to solve objective questions quickly. This book not only covers the syllabus of ESE but

also addresses the need of many other competitive examinations. Topics like ‘Introduction to ICT,

Components of ICT, ICT in Education Technology, ICT & e-Governance and ICT in Networking’ are

given full emphasis, keeping in mind of our research on their importance in competitive examinations.

We have put in our sincere efforts to present detailed theory and MCQs without compromising the

accuracy of answers. For the interest of the readers, some notes, do you know and interesting facts

are given in the comprehensive manner. At the end of each chapter, sets of practice question are

given with their keys, that will allow the readers to evaluate their understanding of the topics and

sharper their question solving skills.

Our team has made their best efforts to remove all possible errors of any kind. Nonetheless, we would

highly appreciate and acknowledge if you find and share with us any printing and conceptual errors.

It is impossible to thank all the individuals who helped us, but we would like to sincerely thank all

the authors, editors and reviewers for putting in their efforts to publish this book.
