Computer programs such as web browser, word processing, spreadsheet, database, presentation and graphics software are called application software. Applications are separate from the operating system software but must be compatible with it in order to be able to operate. For example some applications will only run under Windows. Files will only open if they are compatible with the system software used.
Word Processing applications allow text to be typed, formated, amended, printed and saved as a file (document), which can be reused as many times as necessary.
Spreadsheet applications is a worksheet in the form of rows and columns where text, numbers and calculations can be entered. Spreadsheets allow numbers to be amended and the calculations to be updated taking into account the changes.
Database applications store large quantities of data that can be queried to display only specific information. A database contains multiple fields and records. A field is a column of similar data such as number plates. A record is a collection of associated data, e.g. a row containing entries that relate to an individual person or a company as an example.
Desktop Publishing (DTP) are applications that use graphic design to allow greater control over the layout of pages and the appearance of text and graphics. DTP applications are used rather than word processors to create flyers, posters, cards and newsletters because of the ease of using graphics and text together. Some formatting features within DTP applications can also be found in word processing.
Presentation applications allow sophisticated presentations to be created for use as projections, slides, Web pages or as an on screen display with the option of incorporating audio and video effects.
Web Browsing applications allow users to access the mostly free information on the Internet. Also search for, view and download text and images from the vast collection of data which comprises the World Wide Web.
