The development of an application isn’t the last part, where the job of the developers ends. Most of us think that, this is where the work comes to an end and we are highly mistaken, here. After an application is launched, the creators also have to take care of the way it functions. That is where the role of supporting and maintaining an application, comes in the picture. Developers have to resolve the minutest errors that might occur, as well as continue the functioning of an application without any glitches. That results in satisfactory usage of an application by the end users.
