Computers have become an integral part of our education system. Computer Science is now not limited to just teaching definitions and commands. Instead, it helps the learners to understand and appreciate the varied uses of computers and its vast applications. Trackpad iPRO (Ver. 4.0) series based on Windows 10 and MS Office 2019 is comprehensively designed as per the new ICSE syllabus. We believe computer education is a hands-on subject and too much of bookish knowledge can take away the pleasure of learning. All these points have been kept in mind while designing this book and to produce the content that is not only appealing but also challenging to the students. The topics in the book have been hand picked after extensive research by a team of experts on the subject based on the utility, interest, skill, and basic and trending applications in the global market. We have designed the lessons in such a way that they can be well integrated with other subjects. Step by step approach will make it simple and easy for our students to grasp the concepts. Relevance of the topics was of prime importance throughout the compilation of the book. Learning is done best when it’s fun-filled and activity-based. To ensure that the content intrigues the students at all times and keeps them interested throughout the course of the book, we have included interesting key features like Student Corner, Tech Funda, Clickipedia, Comp Caution, Reboot, One Touch Learn, Let’s Do It, Crack The Code, Hands-On, Fun In Lab, Teacher’s Corner, Worksheet, Test Sheet, Project, Speech Drill, Supplement Pages and Glossary. These features will ensure better learning, assessment, and evaluation and enable children to take their knowledge beyond the classroom. Sample questions of Orange Global Olympiad (Cyber) have been included to promote awareness about the national level competition. We hope that the book contributes to the progressive development of computer aided education system and prepares our students for all upcoming challenges. We want the children to learn the concepts not only for the purpose of gaining knowledge but also to be able to find their applications. This will enable them to enrich the quality of their lives as well as others’.
