Modern advancements and developments in the field of computer have brought the world into  new era. Computer has emerged as a powerful tool that is continuously transforming the shape  of our working methodologies and day-to-day services. There is hardly any sphere of life left  now, in which computers are not being used. Be it any area of operations, computer knowledge  is must. This is the reason, why most of the education institutions have introduced computer as a subject in  their course curriculum. Board of Technical Education (B.T.E.) UP (Lucknow) suggests study of  Computer Applications in first year of all polytechnic branches. 

This book is specially written for first year polytechnic students of all those polytechnic institutions,  which are affiliated to UP Board of Technical Education. It is exactly as per syllabus suggested by  B.T.E. and takes care of all the subjects, topics and practical assignments mentioned therein. However, at  some places, sequence of the topics has been slightly changed with the objective of explaining the topics in  gradual manner and making the learning easy. Readers will definitely appreciate this change, when they go  through the book. 

The language of the book is very easy and never becomes barrier in learning. We have followed American English pattern in this book. Some of the spellings like colour, centre etc. may appear as color, center etc.  They are wrong as per British pattern but are correct in American pattern. We are sure that students and  teachers will appreciate this change because software packages mentioned in the syllabus also follow the  same language pattern. 

This book titled, "Computer Application For Engineering" comprises of 13 chapters. Each chapter  explains the subject in detail and interesting manner. To make the explanation more meaningful, lots of  examples and figures have been included in each chapter. This aspect has emerged as main strength of the  book. 

At the end of each chapter, a question bank, titled "Exercises" is there. All the questions put together, cover  all important aspects of the topic. Solving these questions correctly, on self-knowledge basis, will generate  confidence and ensure good marks in the examination. 

After exercises, practical assignments are given for computer lab sessions. Each lab assignment includes  step-by-step instructions for doing practical on computer. Following these instructions, students will be  able to complete a mini project. They will learn practical aspects of computer applications and will sharpen  their skills by completing the given assignments. 

We are sure that this book will serve as perfect teaching guide for the teachers and good reference book for  the students. It is expected that they will take full advantage of our knowledge and experience. 

Although enough care has been taken to make the book error free but some mistakes may have gone  unnoticed. Feedbacks and suggestions in this regard, on our address, will be highly appreciated.
