Software Development Overview

[Stiven]

Let's first understand what software development means. The term consists of two words, software and hardware.
Software is more than just software code. A program is an executable code that performs some computational tasks. Software is considered to be a collection of executable program code, related libraries, and documentation. Software, if it is made for a specific requirement, is called a software product.
On the other hand, engineering is the development of products using well-defined scientific principles and methods.
The process of developing a software product using principles and methods of software development is called software evolution. This includes initial software development, maintenance, and upgrades until the desired software product is developed that meets the expected requirements.
