Laboratory Learning Activities: Practicing Windows Basics
In order to be able to perform various tasks such as saving files, printing documents, and
starting programs, a computer requires software called an operating system. Microsoft
Windows is one of the most widely used operating system. Over the years there have been
several versions of Microsoft Operating System in use such as Windows 3.1, Windows 95,
Windows 98, Windows 2000, Windows XP, and Windows Vista, etc. Regardless of the version,
they all have the same basic functionality. The purpose of this hands-on lab is to provide
an introduction to the Windows Operating System. Hands-on tasks will be identified by the
symbol. When a computer is powered on, you’ll hear some beeping as it does some hardware
checks, and then the operating system loads. A computer running the Windows Operating
System may display a login screen, or it may show the desktop immediately, depending on the
setup.
