Application software allows computers to perform useful tasks like word processing, spreadsheets, databases, presentations, and multimedia. There are several types of application software including word processing software like MS Word, spreadsheet software like Excel, database software like MS Access, presentation software like PowerPoint, and multimedia software like media players. Application software can be commercial, requiring purchase of a license, shareware which is free to use on a trial basis, or freeware which is given away for free by the producer. Software can either be installed directly on a user's computer hard drive or accessed through a web browser. Related application programs are often bundled and sold together as a software suite like Microsoft Office.
