Operating System(OS) is defined as a computer software that makes it easier for human to interact with the computer.
Up to date there are about four(4) popular operating systems in used:
Namely:
a)Unix Operating system
b) Window operating system
c) Linux operating system , and
d) Mac Operating System.
a)Unix Operating system
b) Window operating system
c) Linux operating system , and
d) Mac Operating System.
Below are detail explain actions of each of the above listed popular operating systems and their features.
Windows Operating System:
Window OS possesses the following features and characteristics:
1. There is an Impeccable Human-computer operability of the Windows operating system.
Operating system is a platform for people to communicate with computer hardware. Without good man-machine operability, it is difficult to attract users to use it. In the field of mobile phones, Nokia mobile phones can occupy half of the mobile phone market. Good interactivity of mobile phone operating system is one of the important factors for its success, and its rapid decline is also due to the outdated operating system. Windows operating system can be regarded as the mainstream operating system of personal computer, and its excellent man-machine operability is an important factor. Windows operating system has friendly interface, beautiful window production, easy to learn operation action, good inheritance between multiple generations of the system, computer resource management efficiency is higher, better effect.
2. There are many applications supported by Windows operating system.
As an excellent operating system, Windows operating system is controlled by The Microsoft company which develops the operating system, and the design exposes the standard. Therefore, a large number of commercial companies develop commercial software on this operating system. The large number of applications in the Windows operating system provide convenience to customers. These application software categories, complete functions, good user experience. For example, Windows operating system has a large number of multimedia applications to collect and manage multimedia resources. Customers only need to use these commercial software developed based on the system to enjoy the happiness brought by multimedia.
3. Windows operating system supports hardware well.
Good adaptability of hardware is an important feature of Windows operating system. Windows operating system supports a variety of hardware platforms for the broad and free development environment of hardware manufacturers, which encourages these hardware companies to choose to match Windows operating system, and also encourages the continuous improvement and improvement of Windows operating system. At the same time, the improvement of hardware technology also provides support for the functional expansion of operating system. In addition, the operating system supports a variety of hardware hot plugging, convenient for users to use, has also been welcomed by the majority of users.
Here are the advantages of the Windows operating system:
(1) Intuitive, efficient object-oriented graphical user interface, easy to learn and use
The user interface is uniform, friendly and beautiful
Rich in equipment independent of graphic operations
(4) Multitask operating environment
Unix operating system
1. High reliability: practice shows that UNIX is one of the few operating systems that meet the requirements of host reliability, which NetWare, WindowsNT, OS2 and other operating systems can not compare.
2. Highly scalable: Extremely scalable UNIX is the only operating system in the world that runs on laptops, PCS, and even supercomputers. No other operating system can do this.
3. Good openness: This is the most important characteristic of UNIX system, and also the strong vitality of UNIX.
4 network function is strong: this is another important characteristic of UNIX system, especially as the Basis of Internet network technology TCP/IP protocol is developed on UNIX, and has become an inseparable component of UNIX system.
5.UNIX system is a multi-user, multi-tasking time-sharing operating system
6. The system structure of UNIX can be divided into three parts: operating system kernel, system call and application program
7.UNIX systems are mostly written in C
UNIX provides a rich, carefully selected set of system calls
UNIX provides a powerful, programmable Shell language as a user interface
10.UNIX system adopts tree directory structure
11.UNIX system adopts the memory management mechanism of process swapping and the storage mode of request paging
12.UNIX systems provide multiple communication mechanisms
Linux operating system
1. Openness: In particular, follow the open Systems ZHI Interconnection (OSI) International standard.
2. Multiple users: operating system resources can be used by different users. Each user has specific permissions on its own resources (such as files and devices) without affecting each other.
3. Multi-tasking: The computer executes multiple programs at the same time, while each program runs independently.
4. Good user interface: Linux provides users with two interfaces: user interface and system call. Linux also provides a graphical user interface for users. It makes use of mouse, menu, window, roller-slider and other facilities to present the user with an intuitive, easy to operate and friendly graphical interface with strong interaction.
5. Device independence: The operating system treats all external devices as a file. As long as the driver is installed, any user can manipulate and use these devices like a file. Linux is a device-independent operating system with a highly adaptive kernel.
6. Provide rich network functions: The complete built-in network is a major feature of Linux.
7. Reliable security system: Linux adopts many security technical measures, including read and write control, protected subsystems, audit tracking, core authorization, etc., which provide necessary security for users in a network multi-user environment.
8, good portability: the operating system from one platform to another platform to make it can still 挄 ability to run its own way. Linux is a portable operating system that can run in any environment and on any platform, from microcomputers to mainframes.
9. The basic idea of Linux is two things: First, everything is a file; Second, every piece of software has a definite purpose
10, Linux is a free operating system, users can through the network or other free access, and can modify its source code
Fully compliant with POSIX1.0 standard
12. Multi-user, multi-task operating environment; Support multiple platforms
Mac OS operating system
1. Full screen mode is the most important feature in the new version of the operating system. All applications can run in full screen mode
Task Control integrates the Dock and control panel, and allows you to view various applications in window and full-screen mode
The quick start panel works exactly the same as the iPad, so it displays all the apps installed on the computer with an ipad-like user interface, and is managed through the App Store. Users can swipe their mouse to switch between multiple App icon interfaces
4. The Mac App Store works in the same way as the iOS App Store, with the same navigation bar and management mode
Windows Operating System:
