Software is a set of programs, programs are a set of instructions so in order to communicate the system we are required the grew the systems. So those set up of instructions required as a single program and such number of programs required as a software. A software categorizes into two systems software and application software. They are both software but the uses are different the system’s software the name indicates so the user will interact with the computer, so in order to interact with the computer we required some interface so such a type of interface is called system software. So the software which makes the interaction between the user and the computer is called the system software. The best example of the system software is an operating system. So if the user wants to communicate with the computer we required some mediator because we can’t understand the language of the computer.
Application software means the name of self indicates an application that is meant for particular applications, so if you want to listen to music or to watch a video that means a movie then there will be some application in order to play all this so that is called the application software. That means that meant for a complete application. The best example of this is the MS office.
