It outlines two main types: systems software, which is the operating system, and applications software, which commands specific tasks or solves problems. Applications software can be custom software made for large corporations or commercial software for personal use, like writing papers or playing games. It then focuses on Microsoft Windows, describing it as an operating environment between the user and computer that provides user convenience, aesthetics like borders and fonts, an information center for internet activities, and plug-and-play compatibility for added components like sound and video.
