Introduction ➢ What is software? ▪ When we write a program for computer we name it as software. But software is not just a program; many things other than the program are also included in software. Some of the constituted items of software are described below. 1. Program: The program or code itself is definitely included in the software. 2. Data: The data on which the program operates is also considered as part of the software. 3. Documentation: Another very important thing that most of us forget is documentation. All the documents related to the software are also considered as part of the software. So the software is not just the code written in Cobol, Java, Fortran or C++. It also includes the data and all the documentation related to the program. March 21, 2019 Faculty Name: Ifra Amber 2

➢ Software Importance ▪ Undoubtedly software is playing a vital role in all the field of life these days. ▪ Some of the major areas in which software has played an important role are identified as under: 1. Business decision-making: Software systems have played a major role in business where you have to analyze your data and on the basis of that analysis you have to make business decisions. This process of data analysis and decisionmaking has become very accurate and easy by the use of software. 2. Modern scientific investigation and engineering problem solving: Scientific investigations and engineering problem solving require an intensive amount of calculations and data analysis. The accuracy of these analysis is also very important in scientific applications. This process has become very easy and accurate by the use of software. For example software systems are becoming more involved in bioinformatics and the process of DNA decoding is only possible by the use of software systems. Similarly many astronomical observations are being recorded and analyzed by the software systems these days. March 21, 2019 Faculty Name: Ifra Amber 3

3. 4. Games: We see many computer games these days that interests people of all ages. All these games are drive through software systems. Embedded systems: We see many kinds of gadgets being employed in our daily used things, like small microcontrollers used in our cars, televisions, microwave ovens etc. All these systems are controlled through the software.
