APPLICATION SOFTWARE

System software performs essential support functions. Among these software products are operating systems, language translators, utility programms, performance monitoring programms.

However, application software also referred asproductivity software are developed to help the user to increase his/her productivity. Originally application software was developed by the organizations that owned computers. They have their own programmers to create programms according to their needs. Later, the companies that manufactured the computers began to develope and sell software packages along with their computers. These solutions packages were designed for the kinds of data management tasks that most organizations had, business related activities such as record keeping, inventory control, and payroll accounting.

Eventually, some firms began to sell software that deal with common computer tasks. There has been a tremendous increase in the use of application software packages with the development of microcomputers. Two factors are largely responsible:
  1. The increased cost of developing one's application software.
  2. The irse in the popularity of microcomputers.
Individuals and small businesses wanted specialized programms for creating letters and memos or for calculating their monthly budget. At first PC application programms were designed to create letters and memos and the electronic spreadsheet was created to manage numerical data. But as PC programmers deicovered new ways to use their computers, they began to design and sell an endless variety of specialized software for every type of computer user. Application programms are widely used for entering and editing text (Word processing desktop publishing programms) for entering and manipulating numeric data (spread sheet and many other business programms) and for record keeping (database management programms). These types of programms are sometimes called as general purpose applications.
