Software development is a process that software developers use to build computer programs. The process, also known as the Software Development Life Cycle (SDLC), covers a number of sections that provide a way to build products that meet the specifications of the technology and user needs. It is usually a systematic process with a few steps and stages leading to the creation of operating software. So the good explanation is: “a process with a set of functions that create computer software products, including its design, development, testing, and distribution.” The software itself is a set of algorithms or programs that tell a computer what to do. It is not independent of the hardware and makes the computers organized.
SDLC provides an international standard for software companies to use to build and improve their computer systems. Provides a defined structure for development teams to follow in the design, creation and maintenance of high quality software. The motto of the IT software development process is to build valuable products within a defined budget and timeline.
