Chapter Summary

--- PAGE 1 --- CHAPTER 4 INTRODUCTION TO PROBLEM SOLVING 4.1 Introduction Today, computers are all around us. We use them for doing various tasks in a faster and more accurate manner. For example, using a computer or smartphone, we can book train tickets online. India is a big country and we have an enormous railway network. Thus, railway reservation is a complex task. Making reservation involves information about many aspects, such as details of trains (train type, types of berth and compartments in each train, their schedule, etc.), simultaneous booking of tickets by multiple users and many other related factors. It is only due to the use of computers that today, the booking of the train tickets has become easy. Online booking of train tickets has added to our comfort by enabling us to book tickets from anywhere, anytime. We usually use the term computerisation to indicate the use of computer to develop software in order to automate any routine human task efficiently. Computers…
