In earlier times, software was simple in nature and hence, software development was a simple activity. However, as technology improved, software became more complex and software projects grew larger. Software development now necessitated the presence of a team, which could prepare detailed plans and designs, carry out testing, develop intuitive user interfaces, and integrate all these activities into a system. This new approach led to the emergence of a discipline known as software engineering.
Software engineering provides methods to handle complexities in a software system and enables the development of reliable software systems, which maximize productivity. In addition to the technical aspects of the software development, it also covers management activities which include guiding the team, budgeting, preparing schedules, etc. The notion of software engineering was first proposed in 1968. Since then, software engineering has evolved as a full-fledged engineering discipline, which is accepted as a field involving in-depth study and research. Software engineering methods and tools have been successfully implemented in various applications spread across different walks of life.
Software is defined as a collection of programs, documentation and operating procedures. The Institute of Electrical and Electronic Engineers (IEEE) defines software as a 'collection of computer programs, procedures, rules and associated documentation and data.' It possesses no mass, no volume, and no colour, which makes it a non-degradable entity over a long period. Software does not wear out or get tired.
Software controls, integrates, and manages the hardware components of a computer system. It also instructs the computer what needs to be done to perform a specific task and how it is to be done. For example, software instructs the hardware how to print a document, take input from the user, and display the output.
Computer works only in response to instructions provided externally. Usually, the instructions to perform some intended tasks are organized into a program using a programming language like C, C++, Java, etc., and submitted to computer. Computer interprets and executes these instructions and provides response to the user accordingly. A set of programs intended to provide users with a set of interrelated functionalities is known as a software package. For example, an accounting software package such as Tally provides users the functionality to perform accounting-related activities.
Software Characteristics
Different individuals judge software on different basis. This is because they are involved with the software in different ways. For example, users want the software to perform according to their requirements. Similarly, developers involved in designing, coding, and maintenance of the software evaluate the software by looking at its internal characteristics, before delivering it to the user. Software characteristics are classified into six major components.
• Functionality: Refers to the degree of performance of the software against its intended purpose.
• Reliability: Refers to the ability of the software to provide desired functionality under the given conditions.
• Usability: Refers to the extent to which the software can be used with ease.
• Efficiency: Refers to the ability of the software to use system resources in the most effective and efficient manner.
• Maintainability: Refers to the ease with which the modifications can be made in a software system to extend its functionality, improve its performance, or correct errors.
• Portability: Refers to the ease with which software developers can transfer software from one platform to another, without (or with minimum) changes. In simple terms, it refers to the ability of software to function properly on
