Application software vs. system software

Application software should not be confused with operating system software, which works behind the scenes to run your computer. Application software cannot function without the operating system and includes database, word processing and spreadsheet programs. Compaq recommends using Microsoft® Windows® 7 as your operating system software. Windows 7 is installed on most new Compaq desktop and laptop PCs.

Categories of application software
There is an endless range of programs available for your PC. Software providers often package two or more applications in software suites, available at a discounted price (compared to buying each separately). The Microsoft Office suite, featuring Microsoft Word, Microsoft Excel and Microsoft PowerPoint is a perfect example.
Some other common application categories include:

Installing application software

You can install application software manually using CDs or DVDs provided by the software maker or, if available, by downloading the program online. Some programs, called "shareware," are available free online and can be downloaded at websites like cnet.com. The shareware programs may be trial versions or only offer basic features. When choosing any application software for your PC, make sure you have the hardware and operating system software required for proper performance. These requirements are clearly labeled on the software packaging and at the download website.

Most programs walk you through the installation process with a series of pop-up windows that ask questions about your PC. Often, you'll have a choice to perform a "standard" or "custom" installation. Standard installation will be appropriate for the majority of users. For custom installations, make sure you follow the instructions provided. From organizing and editing your photos to tracking your finances in a spreadsheet to e-mailing friends and family, application software helps you maximize the amazing potential of your PC.
