This textbook is designed to teach a first course in Information
Technology (IT) to all undergraduate students. In view of the
all-pervasive nature of IT in today’s world a decision has been
taken by many universities to introduce IT as a compulsory core
course to all Bachelor’s degree students regardless of their
specialisation. This book is intended for such a course. The
approach taken in this book is to emphasize the fundamental
“Science” of Information Technology rather than a cook book of
skills. Skills can be learnt easily by practice with a computer and
by using instructions given in simple web lessons that have been
cited in the References. The book defines Information Technology as
the technology that is used to acquire, store, organize, process
and disseminate processed data, namely, information. The unique
aspect of the book is to examine processing all types of data:
numbers, text, images, audio and video data. As IT is a rapidly
changing field, we have taken the approach to emphasize reasonably
stable, fundamental concepts on which the technology is built. A
unique feature of the book is the discussion of topics such as
image, audio and video compression technologies from first
principles. We have also described the latest technologies such as
‘e-wallets’ and ‘cloud computing’.The book is suitable for
all Bachelor’s degree students in Science, Arts, Computer
Applications, and Commerce. It is also useful for general reading
to learn about IT and its latest trends. Those who are curious to
know, the principles used to design jpg, mp3 and mpeg4 compression,
the image formats—bmp, tiff, gif, png, and jpg, search engines,
payment systems such as BHIM and Paytm, and cloud computing, to
mention a few of the technologies discussed, will find this book
useful. KEY FEATURES: Provides comprehensive coverage of all basic
concepts of IT from first principles Explains acquisition,
compression, storage, organization, processing and dissemination of
multimedia data Simple explanation of mp3, jpg, and mpeg4
compression Explains how computer networks and the Internet work
and their applications Covers business data processing, World Wide
Web, e-commerce, and IT laws Discusses social impacts of IT and
career opportunities in IT and IT enabled services Designed for
self-study with every chapter starting with learning objectives and
