What is Software Development?
Software development is the process of designing, coding, testing, deploying and maintenance of software applications. These apps are designed to accomplish individual processes or resolve specific problems, and developing them follows a formalized sequence known as the Software Development Lifecycle (SDLC). This lifecycle makes the software efficient, robust, and customized according to users’/stakeholders’ requirements.
Software consists of a set of programs, designed and instructed to perform specific tasks, defined through codes, programming languages incorporated into it. Examples of software include system software that operates hardware and devices, application software for end-user particular tasks, and programming software that helps create more software. The software development process ranges from low-level programming language writing, like assembly instructions, to complex high-level assembly codes.
Software development comprises different roles, such as software engineers, developers, or programmers—all involved in doing fine work guided by someone else. When Software Development started, early programs were stored on physical media, from floppy disks to CDs and DVDs. The modern era, where software is easily downloadable and updated through the internet, marks a significant shift from when most software was born bundling itself with its only hardware.
