Application software, or simply applications, are often called productivity programs or end-user programs because they enable the user to complete tasks such as creating documents, spreadsheets, databases, and publications, doing online research, sending email, designing graphics, running businesses, and even playing games! Application software is specific to the task it is designed for and can be as simple as a calculator application or as complex as a word processing application. When you begin creating a document, the word processing software has already set the margins, font style and size, and the line spacing for you. But you can change these settings, and you have many more formatting options available. For example, the word processor application makes it easy to add color, headings, and pictures or delete, copy, move, and change the document's appearance to suit your needs.
Most employees of an organization are likely to use a handful of software applications that are the same for everyone. For example, almost every computer will have an Internet browser, an office suite with word processing, presentation and spreadsheet programs and some applications to work with multimedia files, like image, audio and video.
However, there are many software applications that are very specific to certain fields or certain professions. For example, the software used on a college campus is likely to be different from the software used by an accounting firm. Let's look at some of these specialized software applications.
