What is the desktop operating system

Desktop operating systems can also be said to be a personal computer system, generally refers to the computer installed on the PC graphics interface operating system software. The operating system is divided into the application domain, has the desktop operating system, the server operating system and the embedded operating system 3 kinds. The desktop operating system is one of the most widely used systems.

Characteristics

1, the desktop operating system is basically based on the keyboard and mouse issued by the command to work, the human action and response in the timing of the request is not very strict.

2, from the application environment, desktop operating systems for a variety of complex applications.

3, the development of the interface, the desktop operating system to provide developers with a "black box", so that developers through a series of standard system call to use the functions of the operating system.

4, desktop operating system relative to the embedded operating system, appears to be relatively large and complex.

User interface

Most OS today contains a graphical user interface. There are several types of older OS that combine the graphical user interface with the core, such as the earliest Windows and Mac OS implementations. This approach provides a faster graphical response capability and is less efficient when implemented without cutting modules, but there are strong side effects, such as a graphics system crash that will cause the entire system to crash, such as the blue screen of death. Many modern OS modules have been modular, separating the secondary systems of the graphics interface from the core (known to be the original design of Linux and Mac OS X, and some extended versions of Windows have finally adopted this approach).

Many OS allow users to install or create any graphics interface they like. Most Unix-and Unix-derived systems (BSD, Linux, and Minix) typically install the X Window System in conjunction with the GNOME or KDE desktop environment. Some OS do not have such a flexible graphical user interface, such as Windows. This type of OS can only change its graphical user interface through additional programs, or it can only change parts such as menu style or color configuration.

The graphical user interface goes with the times, such as Windows makeover its graphical user interface every time a new version is available, and the Mac OS GUI also makes a significant shift when Mac OS X is listed.

Market situation

On the desktop system, the Microsoft Windows family basically controls the entire market, and Linux/bsd/solaris's share is basically not likely to compete with it.
