A computer is not able to perform a task without any instruction. In addition to this, external devices need to communicate. The software solves this problem and provides the computer with the proper instruction to perform any task.
The diagram shows an excellent overview of the software classification. Furthermore, a software can be a system software or an application software, which the diagram display.
Nowadays, the system software is recognised as Operating System (OS), and it is responsible for manipulating data and the communication between the human and the computer.
In order for the computer to understand a user's instruction, the language translation such as the Interpreter "Python" translates the instruction into machine-understandable code.
Without any strategies or methodologies, creating software can become too complex.
However, on the other hand, a "Waterfall" method or an agile method like "Scrum" can organise the whole software development until publication.
