In Software fields we develop two types of applications. They are stand alone applications and distributed applications.

A stand alone application is one which runs in the context of local disk. All stand alone

applications are not sharable. System software and application software comes under stand alone applications.

  • System software is used for developing functionality of hardware devices. Examples are C and ALP (Assembly Language Programming).
  • Application software is used for developing organizations oriented applications. This is also known as backend software’s. Examples are dbase, dbase III plus, FoxPro, oracle versions released till now.
  • Internet software is used for developing distributed applications.

A distributed application is one which can be accessed across the network. Distributed application is also one which runs in the contest of the World Wide Web. To develop distributed applications we must use client-server architecture.
