The article will present some knowledge about operating systems such as the concept, roles, functions, and components of the operating system. The following is the most detailed content about the operating system, please follow along.
What is the Operating System?
Operating system (OS) is software that allows users to run various applications on a computer device with the following tasks: – Ensuring interaction between users and computers – Providing tools and services to coordinate the execution of programs, strictly manage machine resources – Organize their exploitation in a convenient and optimal way.
The Role of the Operating System
A bridge between devices with people and between devices and programs on the computer – The operating system is stored as a separate module on external memory (hard drive, floppy disk, CD …) – System Operator provides services to facilitate the implementation and management of efficiency and memory allocation to any installed software application program.
OS Functions and Components
- Organize communication between users and the system
- Provides resources for programs and implementation organization for those programs
- The organization stores information on external memory and provides tools for searching and accessing information
- Testing and supporting software for peripheral devices to exploit them conveniently and effectively
- Provide users with a convenient interface to use the computer system
- Provides efficient and equitable sharing of resources between users and the system
The operating system should have corresponding programs to ensure the above functions:
- Communication between users and the system via cmd command system imported from the keyboard or through system suggestions controlled by keyboard and mouse
- Manage resources by distributing and recovering resources
- Organize information on external memory to store, search and provide information for other programs to process
Operating System Classification
The operating system has 3 main types:
1. Single-user assignment
Programs are executed one after the other, and when working, only one person can log in to the system. The operating system does not require a high processor.
For example: MS-DOS …
2. Multitask a user
With this type of operating system, only one person can be registered to the system, but it can be activated for the system to execute multiple programs simultaneously. Operating systems of this type are complex and require a powerful processor.
For example Windows 95 operating system
3. Multitasking multiple users
Allow multiple people to be registered in the system. Users can let the system execute multiple programs simultaneously. The operating system is very complex, requiring a powerful processor, large internal memory, and abundant peripherals.
For example Windows 2000 Server
Window Operating System
Windows operating systems with many different versions have long held a unique position in the market share today. What makes Windows special?
1. What is the Windows operating system?
Windows (also known as Microsoft Windows) is the name of an operating system family based on the graphical user interface developed and distributed by Microsoft.
It includes several operating system lines, each of which serves a certain part of the computer industry.
The Windows operating system was born on November 20, 1985, by Microsoft as a graphical interface for MS-DOS in response to the growing user interest with graphical user interfaces.
So far, through many versions with many different changes, the Windows operating system has achieved a lot of success, including Windows XP, Windows 7, and Windows 8 and the latest operating system today.
Windows 10. In addition, other versions of Windows such as Windows 98, Windows 2000, Windows Vista, Windows Server, etc.
2. Strengths of the Windows operating system
- High compatibility:
Because of absolute dominance in market share on Windows operating systems, it has always attracted the attention of hardware manufacturers and software developers. This has resulted in Windows devices and applications also became extremely unique and abundant.
Windows is not comprehensive security such as Linux, Mac OS … but Microsoft still works hard every day to equally provide customers with the latest security patches.
Microsoft always provides users with free upgrade and update packages to optimize the stability and security of your device.
- Support many applications:
Windows fully supports the applications that users need and outperforms other operating systems. The next version of the Windows operating system inherits the basic features of the previous version, making it easy for users to get used to and use it.
- Maximum support for touch screens (Windows 8 and above):
Laptops that support touch screens are operated on Windows 8 or later, the Windows platform has been designed to support touch screen devices.
- Separate application store
Microsoft has invested in an interface that works in tandem with the same Desktop interface, and the special feature on this interface is the application store on Windows.
Recently, the number of applications has started to increase rapidly, and if you own a device with a touch screen, it will be really great to use these applications.
3. Weaknesses of the Windows operating system
Windows operating system always attracts the attention of hackers because the number of users is too large, thus causing problems related to viruses, spyware, malicious code …
The increased security requires users to update regularly and fully, but Windows never stops arising issues.
