Do you know the difference between software application types

Do you know the difference between software application types




Hello my friends, last lesson we explain the first part of computer software and we explain operation systems. Today will explain the second part of software .It will be about software application systems and its types and function of every application .Lets start now 


 Software application

 There are five types of software application like:
  • System Software
  • Commercial Ware
  • Shareware
  • Free Ware
  • Public Ware
 We will explain each type in details 

System Software
 Programs are present on the computer and previously stored on the disc hard when you buy it. When you use the computer for the first time may be needed to enter some information to composition. This is like that we define the type of computer printer connected to it, and if there is a link to the Internet and the like. Some tasks can be added to the system software whenever the need arises. For example, if you change the printer, we need to download additional software for a computer to deal with the new printer.

 Commercial Ware
Programs are offered for sale commercial programs, as a group office programs (Microsoft office). For example, Commercial programs are available for thousands of uses, such as drawing, accounting and business management and editing movies. And commercial software is often licensed to the user rather than just selling the customary way, with surrounding different conditions associated with their use, as described earlier.

Shareware
Many programmers and hobbyists no programs that are available for free. And distribution of these programs may be via the Internet or distributed with cylinder magazines. These programs are usually available for some time before buying. Pay for these programs depend on trust and honor. If the user wants to continue to use the software after the trial period, he must pay fees to the author

Free Ware
Be similar to programs without participation fees are distributed free of charge and is not expected to pay for them and some authors are responsible for the quality of the program. As is the case in the programs available, they also come under some conditions developers may distribute copies initial free so that users feel the usefulness of the program. And often keeps the authors of these programs with all legal rights to their programs. May not be copied or distributed to these programs.

 Public Ware
These programs are available for public use it is available for free and can be copied and modified, there is no fee to use it.



 Now we finish the lesson .Next lesson will be about the difference between programs and application .To be continued
