Application Software Applications are software packages that you use to do your work. For example, a word processor is an application with which you create and modify documents such as business letters and mailing lists.
Applications work at the highest level of computer networking.
You use applications as an interface through which you can access the resources of the computer as well as resources on the network to which your computer is connected. Commonly used application software includes word processing, accounting, spreadsheet, database, and e-mail programs. One important issue to consider when selecting application software is its degree of network and intranetwork integration. Not all applications are designed for network use. To effectively use network and intranet services, application software must be well suited to the computer network environment.
