PREFACE Computer has been recognized as the most life changing and successful invention by man. Its applications have seeped into our lives so deeply that it’s difficult to imagine our lives in its absence. Hence, it is mandatory to impart computer education to the young minds so that they are well-equipped to take over the world of tomorrow.
We believe there can be no set curriculum for computer education because of its dynamic nature and constant evolution on a daily basis. It 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 not only appealing but also challenging to the students.
Touchpad PLAY (Version 1.1) series, based on Windows 7 and MS Office 2010 is designed carefully keeping in mind the overall growth of the child. The topics in the book have been hand picked after an extensive research by a team of experts of the subject based on utility, interest, skill, 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. When our children learn to operate computer systems they will definitely be exposed to a lot of cyber threats so knowledge of cyber security becomes imperative. The students will face a global competition once they step out of the school so they should be updated with the latest technologies like Artificial Intelligence which holds a promising future in the times to come. Introduction of open source software like Tux Paint, Scratch and Python in the curriculum will definitely give our students an edge above others and hence make programming ideas more innovative and creative.
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, Hands-On, Subject Enrichment—Fun In Lab, Teacher’s Corner, Periodic Assessment, Test Sheet, Project Work and Supplement Pages. Sample questions for Orange Global Olympiad (Cyber) have been included to promote awareness about the national level competition. These features will ensure better learning, assessment, evaluation and enable children to take their knowledge beyond the classroom.
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 with not only the purpose of gaining knowledge but also to be able to find its applications. This will enable then to enrich the quality of their lives as well as others.

to learn about: Early Counting Tools Abacus—First Calculating Device Pascaline Adding Machine Leibniz Step Reckoner Charles Babbage’s Analytical Engine Lady Ada Lovelace’s Programs Herman Hollerith’s Tabulating Machine Computer Generations
Dear Students! You have learnt about computers in your previous class.
Computer is a familiar word for you today. But have you ever thought ‘Who invented the computer?’ This machine is an outcome of labour of a number of minds. No particular person can be credited with the invention of computers, but several names stand out in the crowd.
EARLY COUNTING TOOLS Since ancient times, people have invented tools for calculations. Early man tied knots in a rope and carved marks on clay in order to keep the records. They also used to count with the help of fingers, toes, pebbles, stones, sticks, bones, etc.
Early Counting Tools Evolution of Computers

ABACUS—FIRST CALCULATING DEVICE The first step towards computing was the invention of Abacus around 3000 years ago, in China. It is a wooden frame with beads on parallel wires which can do simple calculations like addition and subtraction. This device is used to calculate numbers at a fast speed.
Abacus
Clickipedia
Abacus is also used in schools as an aid in teaching the numeral system.
PASCALINE ADDING MACHINE In 1642, a mathematician, Blaise Pascal invented the calculating machine called the Pascaline adding machine. The numbers were fed into the machine by dialing them on the wheels. This device is believed to be the first mechanical calculator of the world. This machine was capable of performing only addition and subtraction.
Pascaline
Blaise Pascal
LEIBNIZ STEP RECKONER In 1672, a mathematician, Gottfried Wilhelm Leibniz invented the digital mechanical calculator called ‘Step Reckoner’. It was the first calculator that could perform all four arithmetic operations i.e., addition, subtraction, multiplication and division.
Leibniz Step Reckoner
CHARLES BABBAGE’S ANALYTICAL ENGINE In 1822 a mathematician, Charles Babbage developed a steam driven calculating machine, that was the size of a room, which he called the Difference Engine. But even after working on this project for 10 years, this machine never became a reality. Charles Babbage 8
Touchpad PLAY (Version 1.1)-V
Analytical Engine
In 1833, he invented a machine called the Analytical Engine, the first ever working model of a mechanical computer, a fully program controlled machine. This is why Charles Babbage is known as the ‘father of computers’.
LADY ADA LOVELACE’S PROGRAMS The instructions given to Babbage’s Analytical Engine were in the form of 0’s and 1’s and the first person to introduce this concept was Lady Ada Lovelace. Since she was the first to introduce the concept of programming, she is known as the first computer programmer.
Lady Ada Lovelace
HERMAN HOLLERITH’S TABULATING MACHINE Herman Hollerith, an army engineer, built a machine called the Tabulating Machine in 1890. The machine read and stored data from punched cards. After the success of this machine, Hollerith formed a Computing Tabulating Recording Company to sell his machine. Later in 1924, his company became a part of International Business Machines Corporation, today popularly known as IBM.

COMPUTER GENERATIONS After these early calculating machines, the present computer took its shape in five generations.
First Generation (1940s) There were many computers that were a part of first generation computers. MARK-I The First Electro-Mechanical Powered Computer In 1944, Prof. Howard Aikens built the first electro-mechanical computer named Mark-I. It used punched cards and a typewriter for input and output. Mark-I was much more reliable than early electronic computers.
Mark-I
ENIAC—The First Electronic Computer Electronic Numerical Integrator And Computer, was the first electronic general purpose digital computer built in 1946 by John Mauchly and Presper Eckert. It contained over 18,000 vacuum tubes and was 1000 times faster than Mark-I. ENIAC consumed almost 200 kw of power.
ENIAC 10 Touchpad PLAY (Version 1.1)-V
UNIVAC UNIVAC or Universal Automatic Computer, was another successful invention of John Mauchly and Presper Eckert in 1951, which could handle both numeric and textual information.
UNIVAC
The UNIVAC had 5200 vacuum tubes. Features of First Generation Computer Huge in size Very expensive Made up of vacuum tubes
Vacuum tube
Second Generation (1950s) After 1955, use of transistors and magnetic tapes changed the image of the electronic computer. During this period, the major computer manufacturers began to offer a range of accessories such as: Page Printers, Cathode Ray-Tube display, Card Feeders, etc.
Magnetic tape
Features of Second Generation Computer
Transistor
Made up of transistors Magnetic tapes were used to store data Small in size and less expensive than the first generation computer Faster and reliable Evolution of Computers
11
Third Generation (1960s)
In the third generation, the invention of Integrated Circuits (IC) led to smaller-sized computers with better functioning and more storage. Integrated Circuits
Features of Third Generation Computer These computers were made of ICs. The use of the ICs reduced the size and increased the speed of the computers. They were more affordable and dependable.
Fourth Generation (1970s)
In 1980’s, Very Large Scale Integration (VLSI) came into existence in which thousands of transistors were placed on a single chip called microprocessor. IBM released their first line of desktop PC, which used the Intel 8088 chip as their CPU. In 1983, IBM introduced the PC-XT, which had more memory and more hard drive space.
Microprocessor
IBM PC
In 1985, Microsoft released the first version of Microsoft Windows. Features of Fourth Generation Computer VLSI called microprocessors invented Small in size and could be placed on an office table Hard disk to store data Introduction of GUI operating system
12 Touchpad PLAY (Version 1.1)-V
Clickipedia Intel introduced the Intel 4004, the first microprocessor in 1971.
Fifth Generation (Present) After 1986, VLSI technology was used to develop more powerful microprocessors to improve the speed, size, cost and performance of computers. In 1997, Intel introduced the MMX microprocessors, which were designed to improve game and multimedia performance. Scientists are still trying to develop computers with Artificial Intelligence (AI). Features of Fifth Generation Computer Will use artificial intelligence Improved size, cost, speed and performance New versions of GUI operating systems are developed
