from other objects. One of the principal advantages of object-oriented programming techniques over procedural programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. A programmer can simply create a new object that inherits many of itsfeatures from existing objects. This makes object-oriented programs easier to modify. To perform object-oriented programming‚ one needs an object-orientedprogramming language (OOPL)

As computers have become less expensive‚ they have been purchased by more and more families for their homes. As a result‚ more youths and children have started to use computers at earlier ages. Even if there is not a computer available at home‚ it’s guaranteed that the youth will come into contact with a computer somewhere else‚ such as school. This may have not been the case a couple decades ago and with that said‚ computers have been evolving (and still are). The evolution of computers is all possible

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language. Source code is

Introduction to computer Basics Background This topic will discuss the introduction to the use of the computer in the business area‚ including the basic hardware and software concepts. Information technology (IT) is one of the key resources in the modern business environment. We have lived during the past 20 years in a period that has strongly emphasised the strategic importance of information technology. Consequently‚ those currently involved in management have a clear vision of the technology’s

Computer is an electronic device used in almost every field even where it is most unexpected. That is why this age is called as the era of IT. And now we cannot imagine a world without computers. It is made up of two things one is the hardware and other is software. All physical components of computer like keyboard‚ mouse‚ monitor etc comes under the hardware whereas all the programs and languages used by the computer are called software. These days computers are the tools for not only engineers

UNIT-I INTRODUCTION INTRODUCTION TO COMPUTER The term “Computer” is derived from the Latin word “Computare” which means “to compute” or “to calculate”‚ so it is considered to be calculating device. In fact‚ the main objective of inventing the computer was to create a fast calculating machine. But now-a-days more than 75% of non-mathematical or non-numerical work is carried out by the computers. Today‚ computer technology has spread to every sphere of existence of modern man‚ from railway

A computer is an electronic device that can receive a set of instructions or program and the carry out this program by performing calculations on numerical data or by compiling and correlating other forms of information. ("Computer" Encarta). It also performs calculations and processes information with astonishing speed and precision. Computer Technology has improved our lives. It will continue to affect our future which will lead to an easier‚ less complicated lifestyle‚ with more job opportunities
