Windows operating system features

Windows has the following advantages:

• Intuitive and efficient object-oriented graphic user interface, easy to learn and use:

In a sense, Windows user interfaces and development environments are both object-oriented. The user uses the "select object-operation object" Method for work. For example, to open a document, first select the document with the mouse or keyboard, and then select "open" from the right-click menu to open the document. This operation simulates real-world behaviors, which are easy to understand, learn, and use.

• The user interface is unified, friendly, and beautiful:

Windows ApplicationsProgramMost of them comply with the CUA (common user acess) standards proposed by IBM, and all programs have the same or similar basic appearances, including windows, menus, tool bars, etc. As long as you master one of them, it is not difficult to learn other software, thus reducing the cost of user training and learning.

• Various device-independent graphic operations:

Windows Graphics Device Interface (GDI) provides a wide range of graphic operation functions to draw geometric figures such as lines, circles, and frames, and supports various output devices. Device independence means that images of the same effect can be displayed on a dot matrix printer and a high-resolution display.

• Multi-task:

Windows is a multi-task operating environment that allows users to run multiple applications at the same time, or to do several things in one program at the same time. Each program occupies a rectangular area on the screen. This area is called a window, and the window can overlap. You can move these windows, switch between applications, and perform manual and automatic data exchange and communication between programs.

Although the computer can run multiple applications at the same time, only one is active and its title bar is highlighted. An active program is a program that can receive user keyboard input.
