What is operating system

An operating system is a program that manages the computer hardware.It also provides a basis for application programs and acts as an intermediary between the computer user and the computer hardware. An amazing aspect of operating systems is how varied they are in accomplishing these tasks. Mainframe operating system are designed primarily to optimize utilization of hardware. Personal computer (PC) operating systems support complex games, business applications, and everything in between.  Operating systems for handheld computers are designed to provide an environment in which a user can easily interface with the computer to execute programs. Thus, some operating systems are designed to be convenient, others to be efficient, and others some combination of the two.

Windows:

The Microsoft Windows operating system is a set of operating systems developed by Microsoft Corporation of the United States. It was introduced in 1985. It was originally a Microsoft-DOS emulation environment. The subsequent system version was not only easy to use due to continuous update and upgrade by Microsoft, but also slowly became The favorite operating system for every household.

feature：

1. The man-machine operation of the Windows operating system is excellent.
The operating system is a platform for people to use computer hardware to communicate. Without good man-machine operation, it is difficult to attract users. In the field of mobile phones, Nokia mobile phones can occupy half of the mobile phone market. The good interaction of mobile operating systems is one of the important factors for its success, and its rapid decline is also due to the backwardness of the operating system. The Windows operating system can be used as a mainstream operating system for personal computers, and its excellent human-machine operability is an important factor. The Windows operating system has a friendly interface, beautiful window production, easy operation, and good inheritance among multiple generations of systems. The computer resource management efficiency is high and the effect is good.
2. There are many application software supported by the Windows operating system.
The Windows operating system, as an excellent operating system, is controlled by Microsoft's control interface and design for operating systems. Therefore, a large number of commercial companies develop commercial software on the operating system. A large number of application software for the Windows operating system provides convenience for customers. These application softwares are all comprehensive, functional, and user-friendly. For example, the Windows operating system has a large number of multimedia applications, collecting and managing multimedia resources, and customers only need to use these system-based commercial software to enjoy the joy of multimedia.
3. The Windows operating system supports the hardware well.
The good adaptability of hardware is an important feature of the Windows operating system. The Windows operating system supports a variety of hardware platforms for the hardware manufacturer's broad and free development environment, which motivates these hardware companies to choose to match the Windows operating system, and also encourages the continuous improvement and improvement of the Windows operating system. At the same time, the hardware technology is improved. It also provides support for the expansion of operating system functions. In addition, the operating system supports hot plugging of a variety of hardware, which is convenient for users to use, and has also been welcomed by users.

Linux:

Linux is a free-to-use and freely distributed Unix-like operating system. It is a multi-user, multi-tasking, multi-threaded and multi-CPU based operating system based on POSIX and Unix. It runs major Unix tools, applications and network protocols. It supports both 32-bit and 64-bit hardware. Linux inherits Unix's network-centric design philosophy and is a stable multi-user network operating system.

advantage:

1.Linux is composed of many microkernels, and its source code is completely open source;
2.Linux inherits the characteristics of Unix and has very powerful network functions. It supports all Internet protocols, including TCP/IPv4, TCP/IPv6 and link layer topology programs, and can be developed with Unix network features. Protocol stack
3. The Linux system tool chain is complete, and a simple development operation can configure a suitable development environment, which can simplify the development process, reduce the obstacles of the simulation tools in development, and make the system have strong portability.
