Operation System (OS) is one of the most necessary elements of computer system. It is the interface between the computer hardware and the user that facilitates communication as well as coordination between various resources of hardware as well as of software. Most users would find it impossible to use a computer without the use of an operating system.
What is an Operating System?
An OS is a system software that controls the computer hardware and software resources as well as supplies it with various services to computer applications. Simply put, it is a software that comes between a user and computer hardware, which grantees that all the system components complement each other efficiently.
Operations of an Operating System
An OS has main functions that may be divided into some key areas:
1. Process Management
It is the role of the OS to oversee the processes executions, which involve multitasking, scheduling and resource assignments. It makes sure that every program running has adequate time and resources to operate well.
2. Memory Management
It monitors every byte of the memory of a computer and deals with the allocation of memory areas and the release of such areas when programs require.
3. File System Maintenance
The OS has the ability to structure and regulate the ways through which data is stored, retrieved as well as handled on the storage devices. It helps with file permissions, naming, directories and access methods.
4. Device Management
Drivers are used to control all the hardware devices connected on the OS. It regulates and organizes the communication of devices so that they work right.
5. User Interface
Modern OS offers convenient, easy to use interface (either command-line interface (CLI) or graphical user interface (GUI)) to operate the computer system.
6. Access Control and Security
It is through the OS that the data and declaration of the system remains intact given that only authorised users and programs can access the system assets.
Types of Operating Systems
There are several types of operating systems according to their usage and surroundings:
1. Batch Operating System
Typical of the older mainframes, it handles batches of jobs, without the user being involved.
2. Time- Sharing Operating System
Enables several users to share the computer at once because the switching of tasks is fast.
3. Distributed Operating System
Regulates a cluster of discrete computers, and presents them as one system to the user.
4. Embedded Operating System
Targeted to be run in embedded systems such as washing machines, routers or industrial machines that have limited resources.
5. Real-Time Operating System (RTOS)
Applied in systems that demand real-time actions such as medical equipments, robots and spaceships.
6. Mobile ME Operating System
Particularly handmade to be used on mobile gadgets such as smartphones and tablet computers. These are Android and iOS.
Popular Operating Systems
There are a number of operating systems which are ruling the computers world:
- Microsoft windows: It is the most popular operating system in personal computing because of its simple and easy to understand GUI and flexibility of its use.
- macOS: A proprietary operating system of Apple company that has a sleek user interface and effective integration with the products of the company.
- Linux: Open-source, free and has a large following among those developing code, server machines and supercomputers.
- Android: Google-based on the Linux kernel the most popular mobile operating system.
- iOS: Apple iOS that is installed in iPhones and iPads, is renowned in performance and security.
Importance of Operating Systems
The operating system is crucial as it makes the interaction process with the computer easy to the user. It hides the challenges of hardware management, and a developer can develop software without bothering about the underlying hardware information. It also guarantees stability, security and efficiency in systems.
This is in addition to the ability of the modern operating systems to support networking, cloud and virtualization simplifying a wider scope of functions that drive the digital world today.
Future of Operating Systems
Due to the developments in technology, operating systems are currently becoming increasingly efficient, secure and also adaptive. As cloud computing, edge devices and Internet of things (IoT) are growing, operation systems are becoming lighter, distributed, and smarter. The future of operating system development is influenced by optimization running on artificial intelligence, voice control interface, and cross platform compatibility.
Conclusion
To sum up, it should be noted that an operating system is one of the basic parts of any computer device. It is the unseen drive that takes charge of everything that is in memory till the user interaction. Being the basis of digital communication, it is still in development and can be used in everything starting with the personal computers and ending with massive cloud systems, which is why it is one of the most essential discoveries in the field of computer science.
