- Command Line O.S. Because of the memorization and familiarity needed to operate a command line interface new users find it much more difficult to successfully navigate and operate a command line interface. GUI O.S. Although new users may have a difficult at time learning to use the mouse to operate and use a GUI most users pick up this interface much easier when compared to a command line interface. Control Users have much more control of their file system and operating system in a command line interface. For example users can easily copy a specific type of file from one location to another with a one-line command. Although a GUI offers plenty of control of a file system and operating system, often advance users or users who need to do specific task may need to resort to a command line to complete that task Multitasking Speed Although many command line environments are capable of multitasking they do not offer the same ease and ability to view multiple things at once on one screen. Because command line users only need to use their keyboards to navigate a GUI users have windows that enable a user to easily view, control, and manipulate multiple tasks at once and are commonly much faster. A GUI may be easier to use because of the mouse. However using a mouse.
- Starting to Use Windows Operating System: Windows is a GUI operating system developed by Microsoft Corporation. It is widely used in businesses, educational institutes, and research organizations. The first successful series of Windows was Windows 3.x series. Windows 3.x was not an operating system; it was rather an operating environment providing a GUI that runs on top of DOS, replacing the command line interface with a point-and-click system. In 1995, Microsoft released Windows 95, a complete operating system for Personal computers. Windows 98 was an improved version of Windows 95 from Microsoft, released in 1998. Meanwhile Microsoft concentrated on incorporating networking features in Windows. So the company released Windows NT (New Technology) with extensive networking features. Since then, all recent versions of Windows i.e. Windows 2000 (server and professional), and Windows XP are based on NT Technology.
