Test whether you can run a quiz and a movie. Beyond getting your computer configured to view the web-based curriculum, you can use computers to perform many other useful tasks. In business, employees regularly use a set of applications that come in the form of an office suite, such as Microsoft Office. The office applications typically include spreadsheet software, a word processor, database management software, presentation software, and a personal information manager including an email utility. Spreadsheet software contains tables consisting of columns and rows and is often used with formulas to process and analyze data. A word processor is an application used to create and edit text documents. Modern word processors allow the user to create sophisticated documents, which include graphics and richly formatted text. Database software is used to store, maintain, organize, sort, and filter records – a record is a collection of information identified by some common theme, such as customer name. Presentation software is used to design and develop presentations to deliver at meetings, classes, or sales presentations. Personal information managers include such things as email, contact lists, a calendar, and a to do list. Office applications are now as much a part of everyday work today as typewriters were before the personal computer.
